A late Greek form serving as the third-person singular imperative of 'to be'—functionally equivalent to the earlier ἔστω. It expresses command, permission, or wish: 'let it be,' 'may it be so.' The form appears in texts from the third century AD onward, representing linguistic evolution in Koine and later Greek. Like other imperative forms of the verb, it carries performative weight in blessing, decree, and prayer. The simple act of commanding being underscores the creative and authoritative power of speech.
