Small glass or plastic bottles with narrow openings, usually used to hold medicines, perfumes, or other liquids.
From Old French 'viole', from Latin 'vitula', a small glass container. The word has been used for centuries to describe any small vessel designed for storing precious liquids.
Vials show how container design shapes language—the narrow opening isn't just practical for preventing spills, it became the defining feature that made us call them 'vials' instead of just 'bottles.' That design detail literally got a name!
