What does coital mean?
"Coital" is a formal adjective meaning relating to or involving sexual intercourse. It derives from "coitus," the standard clinical Latin-based term for the act itself, and like that noun it belongs primarily to medical, scientific, and sociological registers. You are most likely to encounter it in research literature — phrases such as "coital frequency" appear routinely in demographic and public-health studies — or in clinical and educational texts describing the physiology of sex. Because it is technical rather than colloquial, it sounds precise and detached, avoiding both euphemism and crudity; speakers who use it in casual conversation risk sounding stiff or overly clinical. The word ultimately comes from the Latin verb coire, "to go or come together," formed from the prefix co- ("together") and ire ("to go") — the same verb that gives English "exit," "transit," and "ambition." Its close relative "coition" shares the same origin. For writers seeking an authoritative, neutral register when discussing sexual behavior, "coital" remains the established scholarly choice.

"The medical text described the physiological changes that occur during coital activity."
"Coital" traces back to the Latin verb coire — literally "to go together" — making it a distant cousin of words like "exit" and "ambition," which all spring from the Latin verb ire, "to go."

Etymology of coital
"Coital" derives from the Latin noun coitus, meaning "a coming together" or sexual union, which itself comes from the verb coire — a compound of co- ("together") and ire ("to go"). The Latin root ire has proven remarkably productive in English, also yielding "exit" (from exire, "to go out"), "transit" (from transire, "to go across"), and "ambition" (from ambire, "to go around"). English borrowed "coitus" and its adjectival form "coital" as learned, Latinate terms, keeping them within formal and clinical usage rather than everyday speech.
