hymen

The word 'hymen' was borrowed directly from Greek hymēn (ὑμήν), meaning "membrane" or "thin skin." In Greek mythology, Hymen was also the god of marriage ceremonies, an association that likely influenced the anatomical term's application. The term entered English via Latin hymen in the late 16th century, retaining its specific anatomical sense. The journey from a general Greek word for a thin layer to a precise medical term demonstrates how classical vocabulary was adopted and specialized within scientific and anatomical discourse.

This word is a simplex loanword from Greek. It does not contain separable, meaningful morphemes in its modern English spelling that can be recombined to form other English words.
