What does unchaste mean?

Unchaste is most commonly used to describe someone or something considered sexually immoral, especially according to the teachings of a certain religion.

It can also be used in a more general way to mean morally impure.

The opposite is chaste, which is most commonly used to describe someone who refrains from sexual activity that’s considered immoral.

Where does unchaste come from?

The first records of the word unchaste come from the 1300s. It comes from the Latin castus, meaning “pure.” The word caste comes from the same root. The prefix un- means “not.”

Whether someone is considered morally pure or chaste heavily depends on cultural and religious norms, and the idea of chastity may differ from one religion to another or one person to another. In Christianity, the word unchaste is typically used to describe those who engage in sexual activity outside of marriage or sexual activity without the goal of reproduction. Describing someone as unchaste is a moral judgment, and the person may take offense to this, especially if they don’t believe in the same set of morals. In many religions, the promotion of chastity has traditionally been directed more toward women, leading some people to criticize such lessons as sexist or oppressive.
