What is the opposite gender of gentleman
The opposite gender of gentleman would be a lady. But the opposite of gentleman would be a scoundrel :o)
A Gentleman means a male chovonist. Since chovinism was historically male, there is no female gentleman.
The opposite is a "Gentlewoman" This is an actual word to compliment the term "Gentleman".
I guess I've encountered 'gentlewoman', but it may be mush less common.Lady does the work.
