Imperative of some number and gender is imperfect of the same number and gender without a prefix.
In Hebrew an imperative may be only of 2nd person.
Normally, imperative is formed by adding a suffix to a verb root:
|masculine||none or ה||ו|
Note that the suffixes of imperative are always the same as suffixes of the 2nd person of imperfect. (TODO: About imperfect of 3-weak verbs).
Negative request or demand is expressed with a particle before imperfect (not before an imperative!):
- אל + imperfect (“Don't do it (now)!”)
- לא + imperfect (“Don't do it (ever)!”)
To all forms of imperative and cohortativus (see below) can be added the particle נא (which may be sometimes translated as “please” but more likely describes a connection of the request with a context) and can be translated “therefore”.
