Simplified etymology
Fornication comes from Latin fornix, originally “vault” or “arch.” Because prostitutes in Rome worked beneath certain arches, fornix acquired the sense “brothel,” and in Late Latin it developed into a term for extramarital sex.
Etymology
From Middle English fornicacioun, through Old French from Latin fornicatio, from fornicari ("to have illicit sex"). The Latin verb is related to fornix ("arch, vaulted chamber"), a word also used for brothels associated with vaulted passages.
