Etymology

Origin of degenerate

First recorded in 1485–95; from Latin dēgenerātus “declined,” past participle of dēgenerāre “to decline from an ancestral standard, deteriorate”; equivalent to de- + generate

Explanation

If something degenerates, it gets worse, like a food fight that degenerates to an all-out spaghetti-throwing war. Degenerate can also describe an immoral person — or the behavior of such a person. Whether used as a verb, noun, or adjective, degenerate carries a sense of making worse or declining to a lower state. People who are degenerate, or who exhibit degenerate behavior, are often set apart from others, in part out of fear that their influence will degenerate the morals of the impressionable people around them.
