Etymology

The word "canister" traces back to the Latin canistrum (wicker basket), derived from Greek kanastron (reed basket). The morpheme can reflects the core idea of a container, while -ister and -er are suffixes that evolved to denote objects or tools. Over time, the meaning shifted from woven baskets to modern metallic or plastic containers, influenced by the Industrial Revolution's need for standardized storage.
