Etymology

Origin of insincere

1625–35; < Latin insincērus tainted, dishonest; see in- 3, sincere

Explanation

Someone who's insincere is a little bit fake or phony. Your classmate's insincere apology for interrupting you probably sounds like she doesn't really mean it. When you're insincere, you're not being completely honest. A losing politician often gives an insincere-sounding concession speech, and a teacher who's having a terrible day might wear an insincere smile on her face. The adjective sincere, "coming from genuine, honest feelings," is at the root of insincere — the Latin prefix in, or "not," is combined with sincerus, "sound, pure, or whole."
