What is a wittol?

A wittol is a term used to describe a man who is aware of and accepts his wife's infidelity, often with a sense of resignation or even approval. The Word is derived from an older usage in English, combining "wit" (knowledge) with "toll" (to suffer). Historically, it has connotations of a man who is passive or submissive in the face of his partner's unfaithfulness. The term is relatively obscure and not commonly used in modern language.
