Etymology
The word immoral comes from the prefix im- meaning “not” and the root word moral, which comes from the Latin moralis, meaning “custom” or “proper behavior.” “Moral” entered the English language in the late 14th century, and “immoral” followed in the 17th century as its direct opposite. The Latin root mor- refers to manners and character, so immoral literally means “not in line with proper conduct.” Over time, immoral became associated with deliberate actions that violate widely accepted ethical codes or virtues, especially in religious, legal, or cultural settings.
