noun
woman approaching middle age
A somewhat dated term for a woman in her late 30s to 40s, often with a nuance of being past her prime. Modern usage may be considered impolite or old-fashioned.
彼女はもう中年増だから、若い娘と同じ服は着られないと言った。
She said that because she's already a middle-aged woman, she can't wear the same clothes as young girls.
