Other forms: strumpets
A strumpet is a woman who commits adultery or sleeps around a lot. It's an insult, although an old-fashioned one.
You're more likely to read about strumpets in Shakespeare than anything written recently, because this is an out-of-style word for a woman who commits adultery. You can also call a strumpet an adulteress, hussy, loose woman, or trollop, but it's best to avoid all those terms since they're sexist and offensive.
