ampulla

the word ampulla entered english directly from latin, where it denoted a small, often globular flask with two handles. the latin term is itself a diminutive form, likely related to amphora, a larger two-handled storage jar, though its precise pre-latin origins are uncertain, possibly from greek amphoreus. the semantic journey is straightforward, moving from a general term for a small container in antiquity to a specialized term in historical archaeology and modern anatomy. in anatomical usage, beginning in the renaissance, it was applied to any flask-shaped dilation, logically extending the literal shape of the ancient vessel to describe similar biological structures.

Structure: ampull (flask, bottle) + a (noun suffix) ampull is from latin ampulla, meaning a flask or bottle. the suffix -a is a latin feminine singular noun ending, often retained in english to denote a singular entity.
