fornicate
Engage in coitus
Fornicate means to have sexual intercourse outside of marriage.
The word carries a formal, often religious or legal tone—you're more likely to encounter it in sermons, scripture, or statutes than in casual speech: The preacher warned against fornicating.
The noun fornication refers to the act itself.
