Imperative mood

Imperative mood is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Imperative mood rather than just read about it. In short: The imperative mood is a grammatical mood that forms a command or request. The imperative mood is used to demand or require that an action be performed.

Key takeaways

  • Imperative mood belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Imperative mood to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Imperative mood from memory before moving on to harder problems.

Reference excerpt

The imperative mood is a grammatical mood that forms a command or request. The imperative mood is used to demand or require that an action be performed. It is usually found only in the present tense, second person. They are sometimes called directives, as they include a feature that encodes directive force, and another feature that encodes modality of unrealized interpretation. An example of a verb used in the imperative mood is the English phrase "Go." Such imperatives imply a second-person subject (you), but some other languages also have first- and third-person imperatives, with the meaning of "let's (do something)" or "let them (do something)" (the forms may alternatively be called hortative and jussive). Imperative mood can be denoted by the glossing abbreviation imp. It is one of the irrealis moods.

Formation 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. Occasionally do is not used: Dare not touch me!) 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:

Let me (Let's) see. (internal monologue equivalent to a first person singular imperative) Let us (Let's) go. (equivalent to a first person plural imperative) Let us be heard. (royal we in an equivalent to a first person passive imperative; also constructions like "We are to be heard") Let him/her/it/them run. (equivalent to a third person imperative; constructions with may are also used) Let him/her/it/them be counted. (equivalent to a third person passive imperative)

Other languages Other languages such as Latin, French and German have a greater variety of inflected imperative forms, marked for person and number, their formation often depending on a verb's conjugation pattern. Examples can be found in the specific language sections below. In languages that make a T–V distinction (tu vs. vous, du vs. Sie, tu vs. você, tú vs. usted and vos, etc.) the use of particular forms of the second person imperative may also be dependent on the degree of familiarity between the speaker and the addressee, as with other verb forms. The second person singular imperative often consists of just the stem of the verb, without any ending. For example, Te Reo Māori has the imperative me, which in addition to being put in front of sentences to command (e.g. Me horoi ō ringaringa; "(you must) wash your hands"), is used to assert the imperative mood in sentences that would be translated as "let's (let us)" in English. An example of this is Me haere tāua, which translates to "let us (you and me) go", but the "us" component goes last.

Syntax and negation

Imperative sentences sometimes use different syntax than declarative or other types of clauses. There may also be differences of syntax between affirmative and negative imperative sentences. In some cases the imperative form of the verb is itself different when negated. A distinct negative imperative form is sometimes said to be in prohibitive mood (abbreviated proh). Negative imperatives tell the subject to not do something. They usually begin with the verb "don't" or the negative form of a verb. e.g., example, "Don't be like that." Many languages, even not normally null-subject languages, omit the subject pronoun in imperative sentences, as usually occurs in English (see below). Details of the syntax of imperative sentences in certain other languages, and of differences between affirmative and negative imperatives, can be found in some of the other specific language sections below. In writing, imperative phrases and sentences may terminate in an exclamation mark (!).

Usage Imperatives are used principally for ordering, requesting or advising the listener to do (or not to do) something: "Put down the gun!", "Pass me the sauce", "Don't go too near the tiger." They are also often used for giving instructions as to how to perform a task: "Install the file, then restart your computer". They can sometimes be seen on signs giving orders or warnings "Stop", "Give way", "Do not enter". The use of the imperative mood may be seen as impolite, inappropriate or even offensive in certain circumstances. In polite speech, orders or requests are often phrased instead as questions or statements, rather than as imperatives:

Could you come here for a moment? (more polite than "Come here!") It would be great if you made us a drink. (for "Make us a drink!") I have to ask you to stop. (for "Stop!") Politeness strategies (for instance, indirect speech acts) can seem more appropriate in order not to threaten a conversational partner in their needs of self-determination and territory: according to some strands of politeness theory the partner's negative face should not appear threatened. As well as the replacement of imperatives with other sentence types as discussed above, there also often exist methods of phrasing an imperative in a more polite manner, such as the addition of a word like please; or a phrase like if you could; or substituting one directive for another, as in the change from will to may, e.g., "you will do that" becomes "you may / can do that". Imperatives are also used for speech acts whose function is not primarily to make an order or request, but to give an invitation, give permission, express a wish, make an apology, et cetera:

Worked examples

Example 1 — a first encounter with Imperative mood

Start with the simplest possible case. Write down what Imperative mood claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Imperative mood before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Imperative mood ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Imperative mood

In research
Imperative mood appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Imperative mood in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Imperative mood is common in secondary-school and first-year university syllabi. It links to neighbouring topics Grammatical moods, Verb types, so understanding it makes those chapters shorter.
In everyday life
Look for Imperative mood outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
