Imperative (grammar)

The imperative mood is a grammatical mood that forms commands or requests, including giving permission or declaring a prohibition or any other kind of advice or exhortation.

An example of a verb used in the imperative mood is the English sentence "Please be quiet". Such imperatives imply a second-person subject (you), but some languages also have first- and third-person imperatives, with the meaning of "let's (do something)" or "let him/her/them (do something)" (the forms may alternatively be called cohortative and jussive).

Imperative mood can be denoted by the glossing abbreviation IMP. It is one of the irrealis moods.

Imperative mood is often expressed using special conjugated verb forms. Like other finite verb forms, imperatives often inflect for person and number. Second-person imperatives (used for ordering or requesting performance directly from the person being addressed) are most common, but some languages also have imperative forms for the first and third persons (alternatively called cohortative and jussive respectively).

In English, the imperative is formed using the bare infinitive form of the verb (see English verbs for more details). This is usually also the same as the second-person present indicative form, except in the case of the verb to be, where the imperative is be while the indicative is are. (The present subjunctive always has the same form as the imperative, although it is negated differently – the imperative is negated using do not, as in "Don't touch me!"; see do-support.) The imperative form is understood as being in the second person (the subject pronoun you is usually omitted, although it can be included for emphasis), with no explicit indication of singular or plural. First and third person imperatives are expressed periphrastically, using a construction with the imperative of the verb let:
