Cryptic
adjective /ˈkrɪptɪk/ — Hidden in plain sight — mysterious on purpose.
Definition
Having a meaning that is mysterious or obscure; using codes or hidden meaning; in biology, serving to conceal.
Beyond the definition
Cryptic is different from complicated: complicated things are hard to understand by accident; cryptic things are designed to obscure. A cryptic message, person, or answer has been deliberately coded. The word carries the implication of something deliberately guarded, which makes it both frustrating and compelling.
Origin & history
From Greek kryptikos 'fit for concealing', from kryptos 'hidden' — the same root as crypt, cryptography, and apocrypha.
