I’m talking about the “other woman” – the one who is having an affair with a married man.

English vocabulary gives a variety of words to label that woman, each with a slightly different tone or meaning. For example:

paramour
mistress
concubine
courtesan
doxy
kept woman
other woman
harlot
strumpet

and let’s not forget:
girlfriend
