hortative

The hortative is a group of semantically similar deontic moods in some languages, especially English. Hortative moods encourage or urge. There are seven hortative moods in English: the adhortative, exhortative, suprahortative, cohortative, dehortative, inhortative, and infrahortative. They differ by intensity, attitude (for or against) and in the case of the cohortative, person.

Hortative moods signal the speaker's encouragement or discouragement toward the addressee's bringing about the proposition of an utterance. For this reason hortative constructions can only be used in the first person plural (cohortative) and second person singular and plural (adhortative, exhortative, dehortative, and inhortative).

e.g. Let's go!

• (cohortative) - mutual encouragement to leave
