labiorum

Labiorum is a Latin term that functions as the genitive plural of the noun labium, meaning "lip" or "lip of." In Latin grammar, labium is a neuter noun of the second declension, with the genitive plural form labiorum. Therefore, labiorum translates literally as "of the lips" and is used in possessive or descriptive constructions within Latin phrases.

In scholarly contexts, labiorum appears primarily as part of Latin anatomical or descriptive phrases rather than as a standalone English word. It conveys relationships or attributes tied to lips or lip-like structures when Latin serves as the historical or formal language of description. In modern English writing, the corresponding idea is typically rendered as "of the lips" or, in many cases, replaced by the plural noun labia when referring to the lips themselves.

Linguistically, labiorum illustrates Latin’s method of expressing possession through the genitive case. It is encountered in discussions of Latin declensions, historical medical literature, and taxonomic or descriptive phrases that preserve Latin morphology in scientific naming and description. Its use outside of Latin text is uncommon, and it does not have an independent meaning in contemporary English beyond its function in Latin phrases.
