Etymology

Origin of naive

First recorded in 1645–55; from French, feminine of naïf, Old French naif “natural, instinctive,” from Latin nātīvus native

Explanation

No one likes being called naive, since it means you lack sophistication or street smarts. A person who is too trusting can be criticized for being overly naive: "You're so naive, you think that map you bought online will really lead you to buried treasure!" Naive shares the same root as native, and originally meant "natural" or "not artificial." It can still be used in a more positive meaning when describing a charming lack of artificiality, as in "the naive style of folk art made by an untrained painter."
