A more thorough explanation:

Fornix (for-niks) is a Latin term that has two historical meanings:

1. A brothel
2. Fornication

A brothel is a place where people pay for sexual services. In ancient Rome, fornices were public places where prostitutes worked.

Fornication refers to consensual sexual intercourse between unmarried individuals. In ancient times, it was considered a sin and was often punished severely.

For example, if someone said "I visited a fornix last night," they would be referring to visiting a brothel. If someone said "Fornication is a sin," they would be referring to the act of having sex outside of marriage.

These examples illustrate the historical meanings of the term fornix and how it was used in ancient times.
