Of, relating to, or having the power to convoke; calling together or summoning an assembly.
From 'convoke' (to call together) plus '-ative' (tending to or characterized by). Convoke comes from Latin 'convocare': 'con-' (together) and 'vocare' (to call).
Convocative is a rare technical term—you might find it describing laws or authority that can 'call together' assemblies, but it's rarely used because English prefers simpler terms like 'summoning' or 'convening' in modern speech.
