Enigmatic
adjective /ˌɛnɪɡˈmætɪk/ — Difficult to interpret or understand — deliberately or inherently mysterious.
Definition
Difficult to interpret or understand; mysterious; having an attractive quality of mystery and inscrutability.
Beyond the definition
Enigmatic is the word for the kind of mystery that attracts rather than repels — the person whose depths you can't quite reach, the smile whose meaning you can't quite read. The Mona Lisa's expression is the canonical example: not simply unknown but perpetually unknowable.
Origin & history
From Greek ainigma — riddle (from ainissesthai: to speak in riddles, from ainos: story, proverb) + -ic. The quality of being a riddle — but a riddle that intrigues rather than merely confuses.
