An amr (imperative) asks or commands someone to perform an action. It does not report an event that has already occurred; it directs an addressee to act.
Word / formMeaning / explanation
اِضْرِبْstrike!
اُكْتُبْwrite!
اِجْلِسْsit!
The meaning of a command is shared even though the acts differ. Arabic imperative forms are produced according to morphological rules; changing the translation of a past or imperfect form is not enough.
