What does vesicula mean?
Vesicula is a rare English noun borrowed from Latin for a small bladder and, by extension, a small sac or cavity. In modern technical writing it refers to a minute fluid-filled structure, as in anatomy and histology, or to a gas-containing membrane in certain microorganisms. Because the established English noun is usually vesicle, vesicula tends to sound archival or strongly Latinate rather than everyday. Its interest lies in its transparent morphology: vesica is Latin for bladder, and the diminutive suffix -cula makes the word literally “little bladder.” This helps explain both its anatomical associations and its close relationship to vesicle, vesicular, and vesication. Outside specialist literature, it is chiefly encountered in historical scientific texts or in terminology that deliberately preserves a Latin form.

"The bacterium contains a gas vesicula that helps it remain suspended in water."
The Latin plural is normally retained in technical usage, though vesiculas may occur in English prose.
"Several small vesiculae were visible within the tissue."
Literally a “little bladder,” vesicula preserves the anatomy of its name in miniature.

Where does vesicula come from?
Vesicula is a Latin diminutive of vesica, meaning “bladder,” formed with the suffix -cula. It entered English as a learned term for a small bladder or vesicle and acquired specialized uses in anatomy and biology. Related Latin formations include vesicalis, meaning “of or relating to the bladder,” and vesicator, while the English derivative vesicular preserves the same base.
