v
To perform oral sex on a man.
Etymology
The verb 'fellate' is a modern back-formation from the much older noun 'fellatio,' which entered English in the late 19th century. 'Fellatio' originates from the Latin verb fellare, meaning 'to suck.' This Latin term is believed to have roots in the Proto-Indo-European stem dʰeh₁(y)-, meaning 'to suck, suckle,' which also gave rise to words like 'female' and 'fetus' through the Latin fēlāre (to suckle). The evolution from the literal, biological act of suckling to its specific modern sexual meaning represents a semantic narrowing, a common process in the history of taboo vocabulary.
Analysis
This word is a back-formation from the noun "fellatio," which itself is derived from Latin. It is not productively formed from separable English morphemes and is therefore treated as a simplex unit.
Examples
The explicit scene included an act where one character was instructed to fellate the other.
The vulgar term is a clinical verb used to describe a specific sexual act.
Charges were brought based on allegations that the defendant forced the victim to fellate him.
