Modal Remoteness and Hypotheticality

I was wondering… and I was hoping… often present a request as a thought or hope and soften it. However, the continuous form does not guarantee politeness by itself, and the same sentence may also report a genuine past thought. Choose the form according to the context, intention, and desired level of directness.

Continuous Forms for Cautious Requests and Suggestions

1. Distancing, Not Shifting into the Past

I was wondering whether you could help often introduces a current request. The past form can create cautious distance here. At the same time, the speaker may genuinely have thought about it earlier: the literal past meaning and the polite function can coexist.

The continuous form presents a thought as a process and can soften an address in such established expressions. It does not prove that the thought is continuing now or that no decision has been made, and it does not automatically make refusal easy. Tone, relationships, and the content of the request also matter.

I was wondering whether the rota could be posted a day earlier.

I wanted to ask whether the rota could be posted a day earlier.

The request concerns the current working arrangement; the past form does not specify a time but distances the request from the moment of speaking.

I wonder whether the rota can be posted a day earlier.

I wonder whether the rota can be posted a day earlier.

The same question in the present tense: more direct and closer to an answer about “now.”

2. Form: A Chain of Several Links

A typical chain consists of three parts: the subject I or we, the past progressive of a verb describing a mental action or expectation (was wondering, were hoping, was thinking), and a dependent clause with a remote modal verb (could, might, would) and the base form.

Could, might, or would often complete the cautious expression, but they are not required: I was hoping you had the address is a correct sentence. Can or will are also possible when the speaker keeps a present perspective. After could / might / would, the base form without to is required.

How to build it

I was / we were + wondering / hoping / thinking + dependent clause; e.g. whether + subject + could + V1 (base form of the verb)

subject / S
—
The grammatical subject: who or what the clause is about; the verb agrees with it. In The book was written, the book is the subject, although someone else does the action.
verb / V
—
A word for an action or state, such as work or be. The pattern determines its form.
V1 / base form
—
The base verb without to: work, go, be.
clause
—
A construction with a verb, often with its own subject: when I arrived. A non-finite clause may leave the subject unspoken: to get home.

We were hoping that the committee might look at the proposal again.

We were hoping that the committee might look at the proposal again.

Were hoping + might + V1: the past progressive and the remote modal form work together as one unit.

I was thinking the two teams could share one office for a month.

I thought that the two teams could share one office for a month.

The suggestion is presented as a thought, so colleagues are free to disagree.

I was wondering if there would be room for one more.

I wonder whether there will be room for one more.

Would be in the dependent clause maintains the same distance.

3. A Scale of Directness

I want directly names a desire; I hope and I’m hoping present a hope, while I was hoping can add cautious distance. I was hoping you might… layers two softening devices. These are typical nuances, not a fixed politeness scale: the same words can sound forceful or ironic.

The simple past form I wondered if… is also polite, but wording with was wondering more often sounds like a thought spoken aloud rather than a ready-made question. The difference is subtle, so the choice depends on how much room the speaker wants to leave for refusal.

I'm hoping you can review the layout today.

I’m hoping you can review the layout today.

The present continuous presents the hope as current; in this context, it can soften the request.

I was hoping you could review the layout today.

I was hoping you could review the layout today.

Was hoping and could often make the request more cautious; the actual freedom to refuse depends on the situation.

I wondered if you could review the layout today.

I wondered if you could review the layout today.

The simple past is also polite, but it sounds less like a thought in progress.

4. Which Verbs Are Suitable

The cautious progressive works with verbs that describe a mental action or expectation: wonder, hope, think. This also includes look in questions such as Were you looking for…?, when referring to the other person’s likely intention. Just is also commonly added: I was just wondering…

Stative verbs such as know or own do not have the progressive form in this meaning: there is no I was knowing. If you want to express knowledge, use the simple form knew; if caution is needed, choose a verb describing a mental action.

Were you looking for the accounts office?

Were you looking for the accounts office?

The past progressive is used in a question to someone who is clearly lost: the other person does not have to give a definite answer.

I was just thinking it might be quicker to phone him.

I was just thinking it might be quicker to phone him.

Just softens the suggestion even further; might follows thinking.

I was wondering who might be free on Wednesday.

I was wondering who might be free on Wednesday.

The past progressive can also combine with a wh-question, not only with if/whether.

5. Will you be… and would be…

Will you be passing the post office? can ask about the expected course of events or plans and serve as an introduction to a request. This does not mean that the plans have definitely been arranged, and it does not guarantee an absence of pressure.

Would you be coming…? can be a cautious question or depend on an imagined condition. In that job I would be working at weekends describes hypothetical regular work. The context determines the meaning.

How to build it

Will you be + -ing? | Would you be + -ing? | would be + -ing (an imagined continuous state)

V-ing / -ing
—
The verb form ending in -ing: working, going. Its role depends on the construction.

Will you be passing the post office on your way home?

Will you be passing the post office on your way home?

A question about plans; the request (whether you could take a letter) can be made after the answer.

Would you be staying for the whole conference?

Would you be staying for the whole conference?

Would adds even more distance than will and leaves room for any answer.

In that role I would be working most weekends.

In this role I would be working most weekends.

An imagined ongoing situation: would be + -ing describes a hypothetical norm.

6. Literal Progressive or Polite Progressive

Context helps distinguish a narrative from a speech act. All afternoon or when the phone rang indicates a past process, while the following question may function as a request. These meanings can coexist: I was wondering all afternoon if you could help me tomorrow may be both a true report and a current request.

Ask what the speaker is doing now: only describing a past thought, or also requesting, suggesting, or clarifying something. Do not classify the form automatically based only on whether a time marker is present.

She was checking the figures all afternoon.

She was checking the figures all afternoon.

All afternoon sets the boundaries: this is a literal action, not softening.

I was waiting for the train when you called.

I was waiting for the train when you called.

The event that interrupted the action makes the meaning literal.

I was wondering about the figures all afternoon, so I rang you.

I was thinking about the figures all afternoon, so I called you.

The same verb, but with duration: this is a report of a past process, not a request.

7. When Caution Gets in the Way

A cautious form is optional. An urgent instruction requires clarity; a delicate approach may benefit from distance. Layering several softeners can sometimes sound affected, but there is no universally acceptable number.

Scope of the rule: here we consider the progressive as a means of caution. Past forms for an imagined present (wish, if only, it's time) and degrees of hypotheticality belong to neighboring rules in this topic.

The bridge is closed. Use the north road.

The bridge is closed. Use the north road.

Direct information and an instruction: caution is unnecessary in this situation.

I was wondering whether we might possibly consider, at some point, perhaps, a different supplier.

I wonder whether we might possibly consider, at some point, perhaps, a different supplier.

The sentence is grammatical, but numerous softeners can overload an everyday approach. Shorten it according to the situation; there is no rule requiring “exactly two links.”

Common mistakes

Incorrect:I was hoping we could arranged the visit on Friday.

Correct:I was hoping we could arrange the visit on Friday.

After could, the base form arrange is required. Hoping itself does not require a modal verb in every dependent clause.

Incorrect:I was knowing you might be busy, so I waited.

Correct:I knew you might be busy, so I waited.

Know is a stative verb: it is not used in the progressive in this meaning.

Incorrect:I was wondering if you could to look at this.

Correct:I was wondering if you could look at this.

After the modal verb could, the base form without to is used.

Incorrect:Will you using the room at noon?

Correct:Will you be using the room at noon?

In the structure will be + -ing, be cannot be omitted.

Incorrect:I was hoping to asking you for a favour.

Correct:I was hoping to ask you for a favour.

After hoping to, the base form of the infinitive is required, not -ing.

Past forms for a hypothetical present

The idea: a past form as distance from reality

A past form can refer to past time or express modal remoteness: the speaker considers a situation imaginary or less likely, or makes a request more tentatively. This does not always mean that the situation is false or impossible. Identify the time of the event separately from the speaker’s attitude.

In its usual hypothetical reading, If we had a bigger office… describes an alternative to the present office or a future possibility. In an appropriate past context, had could instead refer to past time. The whole situation determines the meaning, not merely the absence of yesterday.

Think of this as imagining an alternative: having a bigger office or wanting someone to work. This helps explain why a past form can describe the present. The idea alone does not tell you where English requires were or where would should be avoided in the condition; those choices depend on the construction.

How to build it

V2 = past form of a verb; in a hypothetical construction it may describe the present or future

verb / V
—
A word for an action or state, such as work or be. The pattern determines its form.
V2 / past form
—
The form used in a Past Simple statement: worked, went, saw.

If I had a bigger office, I would hire two more analysts.

If I had a bigger office, I would hire two more analysts.

In the usual reading, had presents an imagined alternative to the present situation; would states its consequence.

I wish the lift worked properly.

I wish the lift worked properly.

Worked concerns a present malfunction; the speaker wants a different state of affairs.

Could you lower the music a little?

Could you lower the music a little?

The request is being made now; could simply distances it from the tone of a command.

If, suppose and imagine: a hypothetical present condition

For a remote condition about the present or future, use a past form in the subordinate clause: if + had / knew / did, or were. In the main clause, use would, could or might + infinitive without to. Would presents the consequence under that condition, could expresses possibility or ability, and might presents a possible consequence. These are not points on a fixed numerical probability scale.

In the ordinary pattern If I knew…, do not replace knew with would. However, would can follow if with other meanings, such as willingness: If you would wait here…. Suppose, supposing, imagine and what if can also introduce imagined scenarios; these need not contradict known facts.

Notice the contrast with an open condition. If the lift stops, we will use the stairs presents a real possibility with the present tense. If the lift stopped, we would use the stairs presents the scenario as more remote.

How to build it

If / Suppose / Imagine + subject + past form, … would / could / might + infinitive without to

subject / S
—
The grammatical subject: who or what the clause is about; the verb agrees with it. In The book was written, the book is the subject, although someone else does the action.
V2 / past form
—
The form used in a Past Simple statement: worked, went, saw.
infinitive
—
The base verb form. With to: to work; without to: work. The pattern determines whether to is needed.

If the committee were more flexible, we could finish by June.

If the committee were more flexible, we could finish by June.

Were is the form of be in the hypothetical condition; could states a possible consequence.

Suppose you had unlimited funding: what would you build first?

Suppose you had unlimited funding: what would you build first?

Suppose introduces an imagined situation, not a question about the past.

If the lift stops, we will use the stairs; if it stopped every day, we would complain.

If the lift stops, we will use the stairs; if it stopped every day, we would complain.

This contrasts an open condition, stops… will, with a remote one, stopped… would.

Wish, if only, would rather and it's time

Wish and if only + past form express a desire for a different present state: I wish I lived closer to the coast. If only is often more emotional. In an unreal meaning, were is possible with every person; conversational was is used with I / he / she / it. With we / you / they, the standard form is were, not was.

Would rather + a different subject + past form describes what the speaker would prefer someone else to do now or later: I'd rather you waited outside. If the subject is the same, use the simple pattern: I'd rather wait outside. It's time / high time / about time + subject + past form means an action should already be started and often conveys criticism: It's high time the council made a decision.

Note the difference: it's time to + infinitive is neutral, as in It's time to go, while it's time + subject + past form suggests that the action is due or overdue. Wish + would for irritating behaviour by someone else is a separate pattern and is not practised here.

How to build it

wish / if only / would rather + subject + past form · it's (high / about) time + subject + past form

subject / S
—
The grammatical subject: who or what the clause is about; the verb agrees with it. In The book was written, the book is the subject, although someone else does the action.
V2 / past form
—
The form used in a Past Simple statement: worked, went, saw.

I wish we lived closer to the coast.

I wish we lived closer to the coast.

Lived concerns a present state: the speaker regrets the current location.

I'd rather you waited outside while we finish.

I'd rather you waited outside while we finish.

The subjects differ, so rather is followed by a past form even though the request concerns the next few minutes.

It's about time the department updated its website.

It's about time the department updated its website.

The past form updated is not about yesterday: the action is overdue.

As if and as though: when to use a past or present form

After as if and as though, use a past form when the speaker considers the comparison false or unlikely: He talks as though he owned the building, although he is not its owner. For situations that may well be true, a present form is natural: It looks as if it is going to rain.

The speaker chooses the form according to their assessment. A sentence without context therefore does not always have one correct option. Exercises on this topic should specify whether the speaker believes the supposition.

In a hypothetical meaning after as if / as though, were is possible with every person. Was is also common with I / he / she / it; this does not permit we was or they was in standard English. The comparisons in these examples concern the present moment.

How to build it

as if / as though + subject + past form (the speaker doubts the comparison) · + present form (quite possible)

subject / S
—
The grammatical subject: who or what the clause is about; the verb agrees with it. In The book was written, the book is the subject, although someone else does the action.
V2 / past form
—
The form used in a Past Simple statement: worked, went, saw.

He behaves as though deadlines meant nothing to him.

He behaves as though deadlines meant nothing to him.

Meant concerns present behaviour; the speaker considers this attitude inappropriate.

It looks as if it is going to snow before we reach the pass.

It looks as if it is going to snow before we reach the pass.

The forecast is quite plausible, so the present form is natural.

She talks as if she were the only expert in the room.

She talks as if she were the only expert in the room.

Were is used with she: the speaker disagrees with her self-assessment.

Were: hypothetical meaning, were to and inversion

Were with I / he / she / it in an unreal condition or after wish is an irrealis form, traditionally also called the past subjunctive. It differs from ordinary past was. Were is especially familiar in If I were you; was also occurs in informal hypothetical usage.

If + subject + were to + infinitive makes a future hypothesis more tentative and formal: If the board were to reject the plan, we would look elsewhere. The speaker is not claiming that this will happen, merely considering the possibility.

In formal writing and speech, you can omit if and put Were first: Were I in your position, I would call her first. Were we to relocate, we would need new permits. Inversion with was, as in Was I…, is not used for this meaning.

How to build it

If + subject + were (to + infinitive) · Were + subject (to + infinitive), … would + infinitive

subject / S
—
The grammatical subject: who or what the clause is about; the verb agrees with it. In The book was written, the book is the subject, although someone else does the action.
infinitive
—
The base verb form. With to: to work; without to: work. The pattern determines whether to is needed.

If I were in your position, I would call her first.

If I were in your position, I would call her first.

Standard were is used with I; the advice is based on an imagined situation.

If the board were to reject the plan, we would look elsewhere.

If the board were to reject the plan, we would look elsewhere.

Were to presents the event as remote: a possibility is entertained, not predicted.

Were I free on Friday, I would gladly attend.

Were I free on Friday, I would gladly attend.

Inversion replaces if: the register is formal and the hypothetical meaning remains.

Modal past forms: could, would and might in requests and suggestions

Could, would and might are related to the past forms of can, will and may, but requests using them can concern the present or future. Could you help? often sounds more tentative than Can you help?. This softens the presentation rather than declaring the request unreal; politeness also depends on tone and context.

Would you mind if I closed the door? therefore concerns the present or immediate future. The past form closed expresses distance, not yesterday. Compare the more direct Do you mind if I close the door?

Scope: progressive forms used for softening, such as I was wondering…, belong to a separate topic on progressive aspect. Patterns for degrees of hypotheticality, including would have + V3 and mixed conditionals, belong to another topic. Here we focus on simple past forms for a hypothetical present.

How to build it

Could / Would / Might + subject + infinitive · Would you mind if + subject + past form

subject / S
—
The grammatical subject: who or what the clause is about; the verb agrees with it. In The book was written, the book is the subject, although someone else does the action.
V2 / past form
—
The form used in a Past Simple statement: worked, went, saw.
infinitive
—
The base verb form. With to: to work; without to: work. The pattern determines whether to is needed.

Would you mind if I borrowed your charger for ten minutes?

Would you mind if I borrowed your charger for ten minutes?

Borrowed requests permission for the next few minutes; the past form softens the tone.

Might I suggest a quieter venue for the call?

Might I suggest a quieter venue for the call?

Might makes the suggestion very formal and tentative.

Do you mind if I sit here? — Would you mind if I sat here?

Do you mind if I sit here? — Would you mind if I sat here?

The pair shows the contrast: the present form sounds direct, while the past form is more remote and polite.

Boundaries: actual past time, wish + past perfect and common mistakes

Yesterday or last year indicates the past time of an event but does not prove that it actually happened: I wish I had known yesterday also describes an unreal alternative. Read the time expressions, construction and context together. A past form after if or as if is not always counterfactual either.

Regret about the past requires the past perfect: I wish I had known means I did not know then. This belongs to the separate topic on degrees of hypotheticality. Compare I wish I knew the answer, meaning I do not know now, with I wish I had known the answer, meaning I did not know then.

Three common learner errors are would in the condition, as in If I would have time…; a present form after wish, as in I wish I have…; and a present or future form after would rather with a different subject, as in I'd rather you will send…. All three are corrected by using a past form in the position expressing remoteness.

I wish I knew the answer, but I was not at yesterday's briefing.

I wish I knew the answer, but I was not at yesterday's briefing.

Knew expresses a present unreal situation; was not at yesterday's briefing describes an actual past fact.

If only the bridge were open; it closed last week.

If only the bridge were open; it closed last week.

Were open expresses a present wish; closed last week describes an actual past event, whose time is indicated by last week.

Common mistakes

Incorrect:If I would have more time, I would join the course.

Correct:If I had more time, I would join the course.

This ordinary hypothetical condition about having time requires had. Would can follow if with certain other meanings, including willingness, but it cannot simply replace had here.

Incorrect:I wish I know her phone number.

Correct:I wish I knew her phone number.

A wish about a present state requires a past form, not a present form.

Incorrect:I would rather you will send the file tonight.

Correct:I would rather you sent the file tonight.

After would rather with a different subject, use a past form even when referring to this evening; do not use will here.

Incorrect:I wish I would live closer to work.

Correct:I wish I lived closer to work.

Wish + would is unsuitable for this wish about your own state. Use a past form for the present state.

Degrees of hypotheticality

A map of remoteness: four reference points

English combines verb forms, modals and context to express hypotheticality. The special form were with I / he / she / it can also mark unreality. Distinguish three questions: when the event happens, how the speaker regards the condition, and how certain they present the consequence as being.

Typical patterns include an open future condition with if + Present Simple and will, may, can or another appropriate result; a remote condition with if + Past Simple and would / could / might; and a remote past condition with if + Past Perfect and would / could / might have + V3. May, might and could can also express possibility without a conditional clause.

These patterns do not form four exact levels of probability. Moving from a present form to a past form can change the time and the content of the scenario itself. A remote form often conveys doubt or politeness; context also determines a counterfactual reading.

How to build it

Present Simple = simple present; Past Simple = simple past; Past Perfect = had + V3; V3 = past participle

V3 / past participle
—
The third verb form: worked, gone, seen. Used after have/has or in the passive, for example; it is not always the same as V2.

If the tender is cancelled, the contractor will sue.

If the tender is cancelled, the contractor will sue.

An open condition: the speaker treats cancellation as a real prospect.

The contractor may sue, and the council might settle.

The contractor may sue, and the council might settle.

May and might allow for possibilities; the difference between them alone does not establish fixed probability levels.

If the tender were cancelled, the contractor would sue.

If the tender were cancelled, the contractor would sue.

An imagined situation: the form is past, but the time is present or future.

If the tender had been cancelled in May, the contractor would have sued by August.

If the tender had been cancelled in May, the contractor would have sued by August.

On the counterfactual reading illustrated here, the tender was not cancelled in May.

Remoteness: time, reality and distance

A past form in a condition does not necessarily refer to past time. In a sentence with Past Simple after if and would in the result, the event concerns the present or future, but the speaker presents it as imagined, unlikely or something they distance themselves from. English grammar calls this remoteness.

In an ordinary third conditional, the Past Perfect presents an alternative past, often understood as something that did not happen. However, had + V3 after if does not always prove that the condition is false: reasoning about unknown past facts is also possible. Read the logic of the entire situation.

The choice of perspective depends on the speaker's stance, not just the facts. The same event may be presented as open when the speaker is insistent, or as imagined when they want to sound gentler or express scepticism.

If the tram stops here, we will save ten minutes.

If the tram stops here, we will save ten minutes.

An open condition: the speaker considers the stop a real possibility.

If the tram stopped here, we would save ten minutes.

If the tram stopped here, we would save ten minutes.

The Past Simple is not about the past here: the speaker imagines a change to the route.

If you sent the form this week, we could still process it in time.

If you sent the form this week, we could still process it in time.

The event is future; the past form makes the proposal more tentative.

Possibility without a condition: may, might, could and would

Modal verbs provide their own nuances. May expresses a real possibility. Might often sounds more cautious: the speaker is less certain or more detached. Could also expresses possibility, often highlighting that an option exists. The difference between may and might is small and is not consistently maintained in British or American usage; context and wording such as though I doubt it are decisive.

When expressing a hypothetical consequence, would relies on a stated or understood condition. In A second shift would clear the backlog, the condition is introducing a second shift. Would also has other uses, such as past habits or the future viewed from the past, without a hypothetical condition.

In reference to the past, these modals can have two different readings. Might have + past participle without a condition expresses uncertainty about facts the speaker does not know. The same sequence in a Past Perfect conditional can describe an unrealised past result. Do not confuse the two.

The inspectors may arrive before noon.

The inspectors may arrive before noon.

May expresses a real possibility.

The inspectors might arrive before noon, though I doubt it.

The inspectors might arrive before noon, though I doubt it.

Might, supported by though I doubt it, highlights the speaker's doubt.

A second shift would clear the backlog.

A second shift would clear the backlog.

Would has an implicit condition: if a second shift were introduced.

The courier might have taken the wrong road; nobody has heard from him.

The courier might have taken the wrong road; nobody has heard from him.

Uncertainty about a past fact, not an unreal condition.

Connecting the condition and result clauses

The conditional clause, or protasis, and main clause, or apodosis, must form a meaningful connection. Do not mechanically require matching time frames: If she had left yesterday, she will be here tomorrow can draw a future conclusion from an assumption about the past. Identify the kind of reasoning first, then the form.

In typical mixed counterfactuals, a past condition has a present consequence, or an enduring characteristic has a past consequence. This is a meaningful combination of times. An error occurs when the form fails to express the intended temporal and logical relationship.

In the standard counterfactual pattern, would does not belong after if: build an unreal past condition with had, not would have. Exceptions include polite requests (If you would wait…) and the meaning “if that would help”; similarly, will after if can express willingness. These are different modal meanings rather than the ordinary counterfactual condition or simple future time.

How to build it

V1 = base form; V3 = past participle; had + V3 = Past Perfect; would have + V3 = a hypothetical past consequence

If the director were less stubborn, the festival would have approved the cut years ago.

A mixed pattern: an enduring characteristic and a past consequence.

If you will wait a moment, I will fetch the manager.

If you will wait a moment, I will fetch the manager.

Will after if expresses willingness, not simply future time.

The force of the consequence: would, might, could

The condition is not the only part that shapes hypotheticality: the consequence can also be made less definite. Would presents the result as expected under the condition, might as possible, and could as an available possibility or capability.

Within the same conditional perspective, replacing would with might changes the meaning: the speaker no longer presents the consequence as expected but merely allows it as a possibility. If a task explicitly specifies a confident or possible result, the answer should match that.

If the supplier had warned us, we would have rerouted the shipment.

If the supplier had warned us, we would have rerouted the shipment.

A confidently presented counterfactual consequence.

If the supplier had warned us, we might have rerouted the shipment.

If the supplier had warned us, we might have rerouted the shipment.

The same conditional perspective, but the consequence is only possible.

If the supplier had warned us, we could have rerouted the shipment.

If the supplier had warned us, we could have rerouted the shipment.

Could highlights that the opportunity would have existed.

Formal signals: should, were to and inversion

Should in a conditional clause often means “if this happens” or “if the need arises”, presenting an event as a possible circumstance. It can emphasise chance or low likelihood, but does not always mean the event is unlikely. Were to formally presents an imagined scenario.

Formal language allows inversion without if: Had + subject + V3 for a counterfactual past, Were + subject + to for an imagined future, and Should + subject + V1 for a possible contingency. The meaning matches the corresponding if-version; the register changes.

If the regulator were to tighten the rules, smaller firms would struggle.

If the regulator were to tighten the rules, smaller firms would struggle.

Were to presents an imagined scenario.

Should you need further details, the clerk will gladly supply them.

Should you need further details, the clerk will gladly supply them.

Should formally introduces a possible need: if further details are needed. It does not prove that such a need is unlikely.

Had the mayor consulted the neighbourhood, the plan would have been amended.

Had the mayor consulted the neighbourhood, the plan would have been amended.

Inversion with Had replaces if…had.

Were the quota to be abolished, imports would rise.

Were the quota to be abolished, imports would rise.

Were … to inversion replaces if … were to.

The speaker's stance: choosing the perspective

First identify the time of the event and the intention. An open condition leaves its fulfilment open; a remote condition presents a scenario with distance; a typical past counterfactual considers an alternative to a known past. Knowledge of the facts matters, but a polite or theoretical presentation also affects the form.

A conditional expression in another language may not distinguish present from past unreality. A sentence about leaving earlier and arriving in time may require either if they left earlier or if they had left earlier. Context is needed: words such as then, last year or now, or knowledge of whether the event has already happened.

Another nuance is scientific caution: a condition with were and would lets a writer test a hypothesis without asserting it.

If you submit the form today, it will reach them on Monday.

If you submit the form today, it will reach them on Monday.

An open condition: the speaker treats the action as a real possibility.

If you submitted the form today, it would reach them on Monday.

If you submitted the form today, it would reach them on Monday.

The same event, presented more gently or with some doubt.

If you had submitted the form on Friday, it would have reached them by Monday.

If you had submitted the form on Friday, it would have reached them by Monday.

On the counterfactual reading illustrated here, the form was not submitted on Friday.

If this theory were correct, we would already see the effect in the data.

If this theory were correct, we would already see the effect in the data.

This rule covers the range of open conditions, possibility, imagined situations and counterfactual past scenarios, and how their clauses fit together. Constructions in which past forms express present wishes or comparisons, such as wish, if only, as if and it's time, belong to the rule on past forms for present hypotheticality.

A separate rule also covers the progressive aspect for tentativeness, as in I was wondering whether you could help. It is mentioned here only as a neighbouring topic and is not practised.

Correct:If the dam fails, the town will flood.

If the intended meaning is a future consequence of a future dam failure, use will flood. Would have flooded expresses a different temporal and modal perspective for which no context is supplied here. Different times in conditionals are not generally forbidden.

Incorrect:If she had taken the earlier train, she would arrived on time.

Correct:If she had taken the earlier train, she would have arrived on time.

A counterfactual past result needs would have + past participle; have cannot be omitted.

Incorrect:Were the chancellor resign, the government would fall.

Correct:Were the chancellor to resign, the government would fall.

Were inversion for this imagined future action requires to + infinitive.
