Scarlet woman is a derogatory term used to describe a woman who is perceived as promiscuous or immoral. There are a variety of synonyms that can be used to describe a woman in this way. Some of the more common synonyms include harlot, strumpet, prostitute, courtesan, and fallen woman. Each of these terms carries with it a negative connotation, and is often used to shame or belittle a woman who has been deemed as behaving in a sexually unacceptable manner. While it is important to be mindful of the language we use to describe others, it is even more important to remember that a woman's sexuality does not define her worth as a person.
