1. More than a command: what the utterance does
An affirmative imperative directs the listener towards an action: read, come in, wait. It does not report what someone usually does. Read the note. addresses the reader, while She reads the note. describes another person’s action.
The word “imperative” names a grammatical form, not necessarily a strict tone. The same structure can give an instruction, advice, an invitation or a good wish. The words and situation determine the meaning; an exclamation mark is not required.
Read the message.
Read the message.
The speaker asks the listener to perform an action rather than describes a habit.
Come in.
Come in.
At an open door, this can be a friendly invitation.
Enjoy your weekend!
Enjoy your weekend!
The form with enjoy expresses a wish, not a demand to relax in a particular way.
2. Start with the base form
For an ordinary short instruction, use the dictionary form of the verb: wait, read, take. Do not add -s, -ed or to before the target verb. The form does not change when you address several people instead of one.
After the verb, add only the necessary details: what to do, where or when. A short imperative can consist of one word. In combinations such as turn off, the particle off remains part of the meaning; turn is the base form.
base verb + necessary details
- 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.
Wait.
Wait.
One word can be a complete utterance; the number of listeners does not change wait.
Take your bag.
Take your bag.
Use take, not takes or to take.
Turn off the radio.
Turn off the radio.
Off indicates switching off; without this particle, the instruction changes meaning.
3. Use be for an instruction about a state
In an affirmative imperative, be also takes its base form. To ask someone to be ready, calm or careful, start with be, not am, is or are. Those finite forms belong to other constructions, such as You are ready.
After be, you can name a desired state with an adjective or specify a place and time. Be at the door at eight. instructs someone to be by the door at eight. Are you at the door? is a grammatical question, but does not give that instruction.
Be + property / place / time
Be careful with this cup.
Be careful with this cup.
Careful describes the desired behaviour; be comes before it.
Be ready at nine.
Be ready at nine.
Be does not change whether you address one person or a group.
4. The listener is understood, but a subject is not forbidden
In an ordinary instruction, the listener is understood from the conversation, so you is usually not written. The instruction can address one person, address them politely or address a group. The English verb remains the same in all these cases.
However, a subject is possible. You stay here. can emphasise that this particular person should stay. Everyone take a seat. addresses the whole group; Someone open the window. asks one of those present to act. These are correct imperatives, not errors caused by including a subject. At beginner level, the main pattern is simpler: no explicitly named subject.
Please wait outside.
Please wait outside.
The recipient may be one person or several; wait does not change.
You stay here.
You stay here.
You singles out the listener and can make the tone firmer; the construction is grammatical.
Everyone take a card.
Everyone take a card.
The imperative address uses take after everyone; it is not the description Everyone takes a card.
5. Politeness, please and emphasis
Please often softens a direct request. Its usual positions are before the verb or at the end of the sentence; other positions are possible depending on the phrase. Do not treat one order as uniquely correct. A word-order task may specify the position only to constrain that particular exercise.
Politeness also depends on intonation, relationships and the situation. Adding please alone does not automatically make a harsh request tactful. Equally, a simple recipe instruction or friendly invitation is not necessarily rude without it.
Sometimes an emphatic do precedes the base form: Do come in. This is a correct way to reinforce an invitation, often with a more formal or particularly welcoming tone. Do is not a required part of an ordinary affirmative imperative.
Please pass the salt.
Please pass the salt.
Please comes before pass and softens the direct request.
Pass the salt, please.
Pass the salt, please.
Final please is also natural; the request’s meaning is preserved.
Do come in.
Do come in.
Do reinforces the invitation; the base form come remains after it.
6. Combine actions and preserve the intention
Several simple instructions can be given in separate sentences or joined with and. If the order matters, first and then help. Every verb in an affirmative imperative stays in its base form. The situation determines the sequence of actions, not the mere presence of imperative sentences.
Distinguish an affirmative instruction from a prohibition and a joint suggestion. Open the box. asks the recipient to open it; Don’t open the box. prohibits it; Let’s open the box. suggests doing it together. All three sentences are grammatical, but perform different functions. Here we mainly practise the first.
For your own answer, choose an action, add the necessary object or place and check the verb form. The model shows one way to say it; a natural synonym, another suitable position of please or a full stop instead of an exclamation mark is not by itself an error.
First read the form. Then sign it.
First read the form. Then sign it.
Two imperatives mark sequential actions: reading must precede signing.
Come in and sit down.
Come in and sit down.
Come and sit are two base forms in one invitation.
Open the box.
Open the box.
This is an affirmative instruction to the recipient, with no prohibition or suggestion to act together.
Common mistakes
Incorrect:Please sits down.
Correct:Please sit down.
When addressing the listener, use the base form sit, without -s.
Incorrect:Please are careful.
Correct:Please be careful.
This imperative needs be before careful; are is a finite form for other constructions.
Incorrect:Do comes in.
Correct:Do come in.
Emphatic do is possible, but it must be followed by the base form come, without -s.
Incorrect:Please open the box and takes a card.
Correct:Please open the box and take a card.
Both actions address the listener: imperative take after and also has no -s.
