An enigma is a mysterious and puzzling situation or thing that's hard to understand. You might encounter an enigma every day, like trying to solve a tricky math problem.
When someone says "enigma", they're usually referring to something or someone that's really tough to figure out. It could be a complicated issue in politics, a brain-twisting puzzle game, or even a person with a very unusual personality. You might hear people talk about the enigma of the universe - trying to understand the mysteries of space and time is like being faced with an enigma every day. Sometimes, when we can't solve something right away, it feels like an enigma.
Something or someone puzzling, mysterious or inexplicable.
