Definition of "jussive"

For example, in the Aaronide blessing, only two of the six verbs are formally jussives, yet all have the same volitional sense.

As far as the jussive goes — ignoring the very few occurrences of this in first person — it can be noted that most of the second-person jussives are in negative commands.

If, on the other hand, reference is made purely to the root, we would expect all frequentative jussives to appear with a front element, producing *mɨt′ət′ɨs instead of mɨt′ət′ɨs (19d).

The jussive and cohortative usually convey more indirect, or more subtle, expressions of volition than the imperative does.
