Adultery

Adultery (from Latin adulterium) is extramarital sex that is considered objectionable on social, religious, moral, or legal grounds. Although the sexual activities that make up adultery vary and the social, religious, and legal consequences, the concept exists in many cultures and is similar in Christianity, Islam, and Judaism. A single act of sexual intercourse suffices to constitute adultery, and a more long-term sexual relationship is sometimes referred to as an affair.
