Giving Instructions

First, Then, Next, After that and Finally show where to begin, what to do next and how to finish a simple set of instructions.

Sequencing words in instructions

Why mark a sequence?

When there are several steps, the reader or listener needs to see their order. Sequencing words act as signposts: First opens the instructions; Then, Next and After that move them forward; Finally marks the end.

These words do not replace the action verb. A marker needs a grammatically complete step after it: an imperative such as open the file, or a sentence with a subject such as you open the file.

How to build it

First, + first step. Then / Next / After that, + next step. Finally, + final step.

First, open the box. Then, take out the cable.

First, open the box. Then, take out the cable.

First marks the beginning, and Then introduces the next action.

Next, connect the cable. Finally, turn on the screen.

Next, connect the cable. Finally, turn on the screen.

Next continues a procedure already started, and Finally names its last step.

Beginning and ending

First identifies the first step in ordered instructions. Do not confuse it with at first, which normally describes an initial situation that later changed rather than command number one.

Place Finally before the last action. In other contexts, finally can mean that something happened after a long wait. In a procedure, its role is clear from the series of steps.

How to build it

First, ... → beginning; Finally, ... → ending

First, choose a language.

First, choose a language.

This is the first action, so First immediately identifies where to start.

Finally, press Send.

Finally, press Send.

Sending finishes the procedure, so Finally is appropriate.

At first, the screen was dark, but then it turned on.

At first, the screen was dark, but then it turned on.

At first describes an initial state and a contrast, not the first command in these instructions.

Then, Next and After that between the start and finish

Then, Next and After that are often interchangeable when simply moving to another step. The choice often depends on rhythm and avoiding repetition.

A gap in the middle of a sequence may therefore have several correct answers unless there are additional constraints. The goal is to show progression, not guess the author's favourite word.

How to build it

Then / Next / After that + next action

Then, add the milk.

Then, add the milk.

Then neutrally continues the sequence.

Next, add the milk.

Next, add the milk.

Next naturally identifies the next step in the same context.

After that, add the milk.

After that, add the milk.

After that explicitly connects the new action to the previous step.

Order rather than reason

In this rule, the markers answer 'what happens next?'. Because introduces a reason, while so often signals a result, conclusion or conversational transition. They can be correct in other sentences, but do not replace a time-order marker when the task is simply to sequence steps.

Do not automatically call a grammatical sentence with because or so incorrect. It may express a different logical relationship or fail the particular exercise's target.

Next, check the address.

Next, check the address.

Next introduces the following action without explaining its reason.

Because the address is wrong, edit it.

Because the address is wrong, edit it.

Because explains why the action is necessary. It gives a reason rather than a step number.

The address is correct, so you can send the form.

The address is correct, so you can send the form.

So links a fact to its result rather than merely marking succession.

The grammatical form of each step

Direct instructions often use imperatives: open, choose, press, wait. You can also explain a process with subject–verb sentences: you open, you choose, you press.

Keep the structure consistent within a short list. If you start with imperatives, continue with imperatives. Do not switch to to open or opening without a grammatical reason.

How to build it

marker + imperative OR marker + subject + finite 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.

First, wash your hands. Then, dry them.

First, wash your hands. Then, dry them.

Both steps use parallel imperative forms: wash and dry.

First, you choose a ticket. Then, you pay.

First, you choose a ticket. Then, you pay.

The subject you and the finite verbs form complete sentences.

Finally, wait for the green light.

Finally, wait for the green light.

Finally is followed by a complete imperative construction, not an isolated to-infinitive.

Commas and marker position

In written learning instructions, placing the marker first and following it with a comma makes the structure visible: First, ...; Next, ...; After that, ...; Finally, ....

A comma after a short, single-word marker such as Then or Next is not always compulsory in actual use. Then press the button and Then, press the button can both be natural. Assess exact punctuation only when the task explicitly asks for it.

Next, open the second file.

Next, open the second file.

The comma clearly separates the introductory marker in a written instruction.

Then press the blue button.

Then press the blue button.

The sentence is also natural without a comma after short Then. Its sequencing meaning is unchanged.

After that, close the window.

After that, close the window.

After the longer introduction After that, a comma helps readers see the boundary between marker and action.

From notes to clear instructions

First establish the actual order of actions. Then add First before the opening step, one or more middle markers, and Finally before the ending. Markers cannot repair an illogical order: for example, a file must be created before it can be sent.

Not every sentence in a short set of instructions needs a marker. Use enough signals to keep listeners oriented, and check that no important step has disappeared.

First, open the form. Next, enter your details. Check the date. Finally, press Submit.

First, open the form. Next, enter your details. Check the date. Finally, press Submit.

The short unmarked step Check the date does not disrupt the clear overall sequence.

First, put the book on the scanner. After that, scan the code. Finally, take your receipt.

First, put the book on the scanner. After that, scan the code. Finally, take your receipt.

The markers support the logical order of a familiar everyday procedure.

Common mistakes

Incorrect:After that, to close the lid.

Correct:After that, close the lid.

An independent imperative step requires base-form close, not a fragment beginning with to.

Incorrect:Next, you pressing the blue button.

Correct:Next, you press the blue button.

The subject you requires finite press. Pressing without an auxiliary does not complete the sentence.

Incorrect:Finally, turn off the computer and closes the window.

Correct:Finally, turn off the computer and close the window.

The two coordinated imperatives need parallel base forms: turn and close.

Incorrect:First, open the form. Then, you to enter your name.

Correct:First, open the form. Then, enter your name.

You to enter lacks a finite verb. In direct instructions, imperative enter is natural.

Imperatives for Instructions

1. An instruction directly names the action

When we explain how to do something, English often begins each step immediately with the action. The listener understands that the instruction is addressed to them, so the usual subject you is not needed.

Imperatives are natural in recipes, directions, short work procedures, device instructions, and warnings. They can sound more direct in a personal request, but this form is familiar in a clear instruction.

How to build it

Base verb + object/detail

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.
object / O
—
Who or what an action affects: in I read a book, a book is the object.

Open the app.

Open the app.

The step begins with the base form Open; the listener is understood from the situation.

Turn left at the bank.

Turn left at the bank.

The imperative names the action Turn and adds a precise direction and place.

2. Affirmative imperative: the base form

The base form of the verb in an instruction does not have to, the ending -s, or -ing: press, check, mix, go. The form does not change depending on whether we are addressing one person or several people.

Add the necessary object and details after the verb. They make the instruction practical to carry out: what to open, where to turn, how much water to add, or how long to wait.

How to build it

Press … / Check … / Mix … / Go …

Check the address before you send the email.

Check the address before you send the email.

Check is the base form; the clause with before specifies when to check the address.

Add 200 ml of water.

Add 200 ml of water.

The quantity makes the short imperative precise without changing the form Add.

3. Negative instructions and warnings

To say what not to do, put Don't before the base form: Don't touch, Don't open, Don't add. After don't, do not use to, -s, or -ing.

The full form Do not is also grammatical and often appears in formal signs. In this material, the main conversational pattern is Don't + base verb; we do not call the full form incorrect.

How to build it

Don't + base verb + object/detail

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.
object / O
—
Who or what an action affects: in I read a book, a book is the object.

Don't open the lid while the machine is on.

Don't open the lid while the machine is on.

Don’t open prohibits opening; the clause with while specifies when the prohibition applies.

Do not use this lift in a fire.

Do not use this lift in a fire.

Do not is the formal full form of the same negative imperative.

4. Sequence and precise details

Several imperatives form a procedure. Markers such as first, then, next, after that, and finally help show the order, but each step still begins with the required verb form.

Not every procedure needs all these markers. If the physical order is obvious, two short sentences are enough; if the steps could be confused, state the sequence clearly.

First, wash your hands. Then cut the vegetables.

First, wash your hands. Then cut the vegetables.

First and Then establish the order, while wash and cut remain base forms.

Wait for five minutes, then press Start.

Wait for five minutes, then press Start.

The duration and the marker then prevent the second step from being done too early.

5. Directness, politeness, and acceptable alternatives

An imperative in a technical or step-by-step instruction usually does not sound too direct. In a personal conversation, you can add please: Please sign here or Sign here, please.

The question Could you sign here? is also grammatical and polite, but it is a different form—a request. If the task specifically asks for an imperative, this question may not meet the learning goal, although the English sentence is correct.

Please close the door.

Please close the door.

Please softens the imperative; the base form close does not change.

Could you close the door?

Could you close the door?

This is a correct polite request, not an example of the base-verb formula without a subject.

6. Limits of the rule and applying it to your own speech

In a demonstration, you can explain a process using the Present Simple: You fold the paper, then you cut here. An imperative can also sometimes have an explicit you for emphasis: You stay here. Here we are practicing an ordinary instruction without an explicit subject; another natural form may not meet this specific condition.

Let’s start is a suggestion for a joint action, while Make sure you save the file is an imperative with the verb make: “Be sure to save the file.” These more complex ways of giving an instruction are also correct, although the focus here is the simple step Open… / Don’t open….

In your own instruction, first identify the goal, then divide the process into doable steps. Check the verb form, necessary object, order, and a safety warning for each step.

You fold the paper like this. Then you cut along the line.

You fold the paper like this. Then you cut along the line.

This is grammatical Present Simple used in a demonstration; it should not be marked as an ungrammatical error.

Fold the paper. Don't cut across the line.

Fold the paper. Don't cut across the line.

The pair combines a positive step with a genuine negative warning.

Common mistakes

Incorrect:Presses the green button.

Correct:Press the green button.

In a complete imperative instruction without a subject, the base form Press is required, not the third-person form presses.

Incorrect:Don't to open the lid.

Correct:Don't open the lid.

After Don't, use the base form without to. The correction does not change the prohibited action.

Incorrect:Doesn't touch the wire.

Correct:Don't touch the wire.

A negative imperative is formed with Don't, whereas doesn't would require a third-person subject in a declarative sentence.

Incorrect:Not add more water.

Correct:Don't add more water.

Not by itself does not form a standard negative imperative; Don't is needed before the base form.

Incorrect:Don't adds any salt.

Correct:Don't add any salt.

After Don't, the verb does not take -s: the base form add is required.

How to make instructions clear

Why highlight an important step?

A simple imperative directly names an action: Close the door. Make sure, Remember to and Be careful to add a reason to pay special attention. They help when a result is essential, a step is easily forgotten or a mistake could cause harm.

These patterns have related but different functions. First identify the intention, then build the continuation: this rule puts a clause with its own subject and verb after Make sure, and a base verb after Remember to or Be careful to.

How to build it

important result → Make sure (that) + subject + verb; reminder → Remember to + base; caution → Be careful (not) to + base

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.

Make sure you have your ticket.

Make sure you have your ticket.

The speaker highlights an essential result before a journey.

Remember to take your ticket.

Remember to take your ticket.

The speaker reminds someone of an easily missed action.

Be careful not to lose your ticket.

Be careful not to lose your ticket.

The speaker warns about an unwanted result.

Make sure (that) + clause

Make sure means checking or ensuring something. Follow it with a complete clause: subject and verb. That is often optional: Make sure that the window is closed and Make sure the window is closed have the same meaning here.

The clause’s subject shows who acts or which result must hold: you save, everyone has, the door is. Make sure you saving is incorrect: you needs finite save, not an -ing form alone.

Make sure to + base verb is also used when the agent is understood and is not a grammatical error. This material specifically practises the transparent A2 Make sure (that) + clause pattern; a task requiring a clause needs a visible subject.

How to build it

Make sure + (that) + subject + finite 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.

Make sure you save your work before closing.

Make sure you save your work before closing.

You is the clause’s subject; save is the correct finite form after it.

Make sure that everyone has a copy.

Make sure that everyone has a copy.

That introduces everyone has a copy and can be omitted.

Make sure the lights are off.

Make sure the lights are off.

The pattern emphasises a required result rather than merely naming an action.

Remember (not) to + base verb

Remember to + base reminds someone to perform an action. After to, use the base form: remember to call, remember to bring, remember to save. Do not add -ing after to.

To remind someone not to act, put not before to: Remember not to share the password. This concerns a prohibited or unwanted action.

Remember + -ing can be grammatical with another meaning: remembering a past event, as in I remember meeting her. It is not an error, but differs from the reminder pattern practised here.

How to build it

Remember + (not) + to + base verb

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.

Remember to bring your passport.

Remember to bring your passport.

Bring takes its base form after to.

Remember not to open this file.

Remember not to open this file.

Not before to makes open the action to avoid.

Please remember to call me at six.

Please remember to call me at six.

Please softens the direct reminder without changing remember to call.

Be careful (not) to + base verb

Be careful to + base asks for attentive performance: Be careful to write the right number. Be careful not to + base warns which action to avoid: Be careful not to press the red button.

The simplest negative warning is careful + not + to + base verb. Careful to not press is also possible, but do not put don’t after to: Be careful to don’t press is incorrect.

Be careful with the glass and Be careful when you cross the road are also grammatical but use different patterns. Here we focus on the to-infinitive and not’s position.

How to build it

Be careful + (not) + to + base verb

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.

Be careful to enter the correct date.

Be careful to enter the correct date.

The positive form asks for particular care when performing enter.

Be careful not to burn yourself.

Be careful not to burn yourself.

Not to burn identifies a risk to avoid.

Please be careful not to wake the baby.

Please be careful not to wake the baby.

Please softens the warning; not stays before to.

Choosing a pattern

Ask what you want to highlight. To check or ensure a required state or result, choose Make sure. For an easily forgotten action, choose Remember to. For care or avoiding risk, choose Be careful (not) to.

A real situation can allow two patterns. Remember to lock the door focuses on remembering the action; Make sure the door is locked focuses on the result. Both are grammatical, with different perspectives.

Remember to lock the door.

Remember to lock the door.

The focus is remembering a future action.

Make sure the door is locked.

Make sure the door is locked.

The focus is checking the door’s final state.

Be careful not to lock the key inside.

Be careful not to lock the key inside.

The focus is a specific unwanted risk.

Clarity is not the same as politeness

These patterns clarify a priority but remain direct instructions. In a work email or conversation, add please, a name or a brief reason if useful: Please remember to send the form today.

Could you close the window? and Please close the window are grammatical, polite alternatives. They are not errors merely because they lack the target pattern. A task explicitly requiring a pattern may reject them for missing its learning target, without making them ungrammatical.

Please remember to send the form today.

Please remember to send the form today.

Please adds politeness while Remember to retains its reminder function.

Could you make sure everyone has the link?

Could you make sure everyone has the link?

The question pattern softens the request; everyone has the link remains a complete clause.

From one sentence to a complete instruction

A good instruction names a specific action, its object and, if needed, a time or reason. Remember to check it is unclear if the other person does not know what it means. Prefer Remember to check the address before you send the parcel.

A short sequence need not begin every step with the same pattern. Use Make sure for a critical result, Remember to for an easily forgotten step and Be careful not to only for a real risk. For longer instructions, provide a way to clarify: If anything is unclear, ask me or call the support number. What do I do next? and Is there anything else? check understanding; lacking the target pattern does not make them errors.

Remember to check the address before you send the parcel.

Remember to check the address before you send the parcel.

The object and time for checking are stated explicitly.

Make sure the lid is closed, and be careful not to press the red button.

Make sure the lid is closed, and be careful not to press the red button.

The first pattern specifies a result; the second separately identifies a risk.

If anything is unclear, call the support number.

If anything is unclear, call the support number.

A channel for questions supplements precise steps and helps check understanding.

Common mistakes

Incorrect:Make sure you saving your work before closing.

Correct:Make sure you save your work before closing.

The clause needs finite save after subject you; saving alone cannot form its predicate.

Incorrect:Make sure that turn off the lights.

Correct:Make sure that you turn off the lights.

The clause after that requires a subject; the smallest correction is adding you.

Incorrect:Remember bring your passport.

Correct:Remember to bring your passport.

A reminder about a future action uses Remember to + base.

Incorrect:Remember to bringing your passport.

Correct:Remember to bring your passport.

Infinitival to requires base-form bring, not bringing.

Incorrect:Be careful not touch the hot pan.

Correct:Be careful not to touch the hot pan.

Do not omit to before the base verb in a negative warning.

Incorrect:Be careful to don't press the red button.

Correct:Be careful not to press the red button.

Not comes before to in this model; to don’t is incorrect.
