1. A desired picture instead of the present one
If only can be rendered as “I wish” or “If only.” The speaker imagines a state of affairs that does not exist now and wants things to be different. This is a wish, not a report that a change has taken place.
The form had in this expression does not say that the person had something yesterday. The context determines the meaning of the situation. More time means more time than there is now, not necessarily a complete lack of time.
If only + subject + Past Simple
- 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.
If only I had more time for reading.
If only I had more time for reading.
There may be some time for reading, but less than the speaker would like.
If only our office had a kitchen.
If only our office had a kitchen.
The office does not currently have a kitchen; had describes a desired present situation.
2. How to form affirmative statements
After if only, we put the subject and then the past form of the verb. With regular verbs, this is usually the form ending in -ed; irregular verbs have their own forms: know → knew, have → had, cost → cost.
We do not add did to an affirmative past form in a neutral sentence. The word order is not interrogative: If only I knew..., not If only did I know....
If only I knew the answer.
If only I knew the answer.
Knew is the form of know for imagined knowledge in the present.
If only this course cost less.
If only this course cost less.
The form cost is the same as the base form; the wish concerns the current price.
If only we lived closer to the station.
If only we lived closer to the station.
Lived describes a desired place of residence, not a former address.
3. Negation: wishing not to have something
When a present action, habit, or obligation is undesirable, we use didn't or did not + the base form of the verb. After didn't, we need have, not had; need, not needed.
The negation belongs to the desired picture. If only I didn't work on Sundays means that the person does work on Sundays but would like not to have that obligation. Do not automatically make every wish affirmative.
If only + subject + didn't / did not + base 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.
- V1 / base form —
- The base verb without to: work, go, be.
If only I didn't have to work today.
If only I didn't have to work today.
The obligation exists now; the negation expresses the desired freedom from it.
If only the lift didn't make so much noise.
If only the lift didn't make so much noise.
This refers to a usual feature of the lift that the speaker would like to change.
4. Be: was and were
For I, he, she, and it, both was and were are possible in such wishes. Were clearly marks the situation as imagined; was is also used and is not an error. For you, we, and they, we use were.
We negate be without did: wasn't / was not or weren't / were not. The choice between was and were does not change the fact that this is a wish about a different present state.
If only I was less busy.
If only I was less busy.
Was is acceptable with I; If only I were less busy has the same basic meaning.
If only she were here.
If only she were here.
Were is acceptable with she; was is also possible.
If only the rooms weren't so small.
If only the rooms weren't so small.
Rooms is plural, so we use were; the negation does not need did.
5. A shade of wishing, not a necessary condition
If only usually sounds more emotional or stronger than I wish, but it does not objectively measure the strength of the feeling. Context and intonation are also important. I wish I lived nearer and If only I lived nearer can express the same wish.
An if only expression can stand alone. You do not need to add a consequence with would. A full stop or an exclamation mark may be used depending on the tone; an exclamation mark does not make the grammar correct.
Compare a wish with a statement: I have a quiet room — the room really is quiet; If only I had a quiet room — the speaker would like to have such a room. The grammatical statement is not an error, but it may not fulfill the task of expressing a wish.
If only the shop opened earlier.
If only the shop opened earlier.
This is a standalone wish about a usual schedule; no second part is needed.
I wish my desk was bigger. If only my desk was bigger!
I wish my desk was bigger. If only my desk was bigger!
The basic wish is the same; the second sentence may sound more emotional, but it does not describe a different fact.
6. Limits of the rule and using it in conversation
Here we practise present states, habits, and obligations. The past form can also refer to a known future state: If only I wasn't busy tomorrow. Therefore, the rule does not mean “any past form = past time.” We do not mechanically put any single future action into the Past Simple.
For regret about a completed past situation, we need a different structure, the Past Perfect. For a desired possibility, could may be used; for a desired change in behavior, would may be used. These are related topics, not incorrect substitutes in every circumstance. A negative wish with couldn't can also be appropriate if the inability itself would be desirable.
In conversation, first identify the desired difference: more of something, a different state, or the absence of an obligation. Then form if only + subject + the appropriate form. If needed, add an ordinary sentence about the reality or the reason; it does not have to contain if only.
The station is a long walk away. If only we lived nearer.
The station is a long walk away. If only we lived nearer.
The first sentence describes reality; the second describes the desired difference.
If only I wasn't busy tomorrow.
If only I wasn't busy tomorrow.
Tomorrow's busyness is already known; was is the past form for an imagined future state. The main practice in the lesson remains about the present.
Common mistakes
Incorrect:If only I didn't knew the password.
Correct:If only I didn't know the password.
After didn't, we need the base form know. The wish not to know the password is possible in the appropriate context; the only error here is the form knew.
Incorrect:If only our flat were be bigger.
Correct:If only our flat were bigger.
Were is already a finite form of be; the additional be is unnecessary.
Incorrect:If only she didn't had to travel so far.
Correct:If only she didn't have to travel so far.
The past form is already expressed by didn't, so we need have after it.
Incorrect:If only we was closer to home.
Correct:If only we were closer to home.
For we, we need were. The acceptability of was with I/he/she/it does not extend to we.
