This term refers to sexual activity between two people who are not married to each other.
The couple engaged in fornication, which is considered a sin in some cultures.
Fornication → It is formed from "fornicari" (meaning to have sexual intercourse) which is derived from "fornix" (meaning arch or vault). The term originally referred to sexual relations that took place under arches or in brothels, hence the modern meaning of illicit sexual activity.
Imagine the idea of sexual relations happening under an 'arch' ('fornix') — this helps you remember that 'fornication' refers to illicit sexual activity.
