What does cunnilingus mean?
Cunnilingus is a clinical noun referring to oral stimulation of a woman's genitals — specifically the vulva — typically performed to give sexual pleasure. It is one of the principal forms of oral sex, alongside fellatio. The word derives from Latin: cunnus, meaning the female genitals, combined with lingua, meaning tongue. Because of this precise anatomical origin, cunnilingus carries a formal, medical register; it appears routinely in sexology, medicine, and sex-education materials, whereas informal English usually prefers phrases such as 'oral sex' or various slang terms. The word functions grammatically as an uncountable noun, so it takes no regular plural, though the adjective 'cunnilingual' exists rarely. Writers and clinicians favor the term because it is explicit without being vulgar, naming the act directly rather than euphemistically. Understanding cunnilingus is useful mainly in health, educational, and literary contexts where accurate, non-slang vocabulary about human sexuality is required.

Etymology of cunnilingus
Cunnilingus entered English in the late 19th century, borrowed from Latin, in which the term was formed from cunnus ('vulva') and lingua ('tongue'), literally describing the act by its means. The same root lingua gives English words such as 'bilingual,' 'language,' and 'linguistics,' while cunnus survives distantly in some learned and slang vocabulary. Its adoption reflects a broader Victorian-era practice of drawing on classical languages to name sexual acts with clinical neutrality.
