From fornication + -s (plural). The word entered English from Medieval Latin 'fornicatio,' and developed its moralizing connotations through religious and legal use from medieval times onward.
In historical texts and religious writings, 'fornications' often appears as a sin listed alongside other transgressions—it shows how seriously past societies judged intimate relationships outside marriage.
