Profane language is the kind that gets bleeped on TV. The word profane can also describe behavior that's deeply offensive because it shows a lack of respect, especially for someone's religious beliefs. The Latin root profanus means unholy, and that's where it all started.
The term profane originates from classical Latin profanus, literally before (outside) the temple. It carried the meaning of either desecrating what is holy or with a secular purpose as early as the 1450s CE.
