Adultery is a word for cheating — cheating on your spouse with another person. Adultery isn’t a crime, but some people consider it a sin.

If two people are dating, and one fools around with someone else, it's not adultery. Only married people can commit adultery. If you commit adultery — and your spouse finds out — then you’ve got a lot of explaining to do. Although it's still highly frowned upon, cultural attitudes toward adultery have changed a lot: the classic book The Scarlet Letter shows how harshly women were once treated for committing adultery.
