Etymology
The word vesicle traces its lineage directly to the Latin noun 'vesica', which meant bladder, a hollow organ for holding fluid. The diminutive suffix, evolving from Latin through Old French, was added to form a term for a small bladder or sac. This literal combination perfectly describes the modern biological and medical meanings: a tiny, membrane-bound sac within a cell or a small blister on the skin. The conceptual journey is straightforward, moving from a general container for liquid to specialized microscopic or small-scale containers in living organisms.
Analysis
vesic originates from latin 'vesica', meaning bladder or blister. le is a diminutive suffix of latin origin, often via french, indicating a small version of something.
