Canister (basket, vessel for liquids, container) comes from the Latin canistrum (wicker basket for bread, fruit, flowers, etc.), which is a transliteration of the Greek canistron/canastron (basket made from reed) from canna (reed; Gr: ). See also post 158 (etymology of cane) here.
In modern Greek (Romeika):
a) canistro or canistra: canister [Gr: κάνιστρο or κανίστρα]
