The Imperative Mood

To create imperative forms of deponent verbs, start with the 2nd person forms of the present tense, i.e., the "YOU" forms.

• To command a single person, remove -is from the 2nd person singular form of the deponent verb and replace it with -e. Thus, loqueris becomes loquere.
• To command two or more, use the 2nd person plural form of the deponent exactly as is. Thus, loquiminî becomes loquiminî.

Cavete! The singular imperative may look like an active infinitive but -- of course -- it can't be because deponent verbs never appear in active form.

Negative Imperative Verb Forms ("Don't do that!"): Use the imperative form of nolo, nolle, nolui, 'not want', followed by the present infinitive of the desired verb.
