Usage

What does enigmatic mean? The adjective enigmatic can be used to describe someone or something that’s puzzling or mysterious. Enigmatic means resembling an enigma—someone or something that’s puzzling, mysterious, or difficult to make sense of. The word enigma can also mean a riddle, but it’s more often used to refer to something that’s so perplexing that it seems like a riddle (and perhaps was intended to seem like one), as in That book is completely enigmatic—I have no idea what it’s really about. If you call a person enigmatic, you mean that they’re hard to figure out—the reasons behind what they say and do are not easily understood. Some people try to be enigmatic to be mysterious. Example: I’ve known him for years, but he’s completely enigmatic—I have no idea what his interests are or what he’s really like.

Origin of enigmatic

First recorded in 1620–30; from Late Latin aenigmaticus, from Greek ainigmatikós, equivalent to ainigmat- (stem of aínigma “riddle, taunt”) + -ikos adjective suffix; see origin at enigma, -ic

Explanation

It's no mystery where the adjective enigmatic comes from: It's rooted in the Greek word for riddle. Something that's enigmatic is obscure, unclear and not an easy nut to crack.
