What does genitalia mean?
Genitalia is a formal, chiefly anatomical noun for the reproductive organs of humans and other animals, especially the external organs. In medical and biological contexts, it names structures associated with sexual reproduction, while in general discussion the more familiar plural “genitals” is often preferred. The word is plural-only in standard modern English, deriving from a Latin neuter plural rather than from an English singular that was later lost. Its register is clinical and precise, though it can sound more technical or explicit than ordinary conversational language. Genitalia is useful when an anatomical or medical distinction is intended, especially in phrases such as external, male, and female genitalia. Despite its clinical tone, the term is not a euphemism: it directly names the organs concerned, and its Latin origin makes it a clear example of an English plural with no commonly used singular counterpart.

Where does genitalia come from?
The word entered English in the early 17th century from Latin genitalia, the neuter plural of genitale. Latin genitale derives from genitalis, meaning “of or for generation,” which is connected with genitus, “begotten”; related English forms include generative, generation, generic, and genital. The Latin plural was borrowed as a plural, so the word has no ordinary singular counterpart in modern English.
