What is "jussive mood"

n. a mood that expresses an intention to influence the listener's behavior [syn: imperative mood, imperative]

The jussive ( abbreviated ) is a grammatical mood of verbs for issuing orders, commanding, or exhorting (within a subjunctive framework). English verbs are not marked for this mood. The mood is similar to the cohortative mood, which typically applies to the first person by appeal to the object's duties and obligations, and the imperative, which applies to the second (by command). The jussive however typically covers the first and third persons. It can also apply to orders by their author's wish in the mandative subjunctive.
