call together
📣 召集 = summon (召) + gather (集) = call people together to convene
召 means to summon or call out; 集 means to gather or collect (the same 集 as in collection). Put them together and you call a group together — convene a meeting or rally the troops.
集 — bird 隹 on top of tree 木
集 is an ideograph showing a bird (隹) perched on a tree (木). The original form depicted three birds gathering on a tree, later simplified to one. From 'birds flocking together' it extended to mean 'gather, collect, assemble,' and by extension 'collection' or 'volume' of writings.
