What does cryptic mean?
Cryptic describes something whose meaning is hidden, obscure, or deliberately difficult to interpret. A cryptic message, glance, or remark conveys less than it seems to, inviting — or frustrating — the effort to decode it. The word derives from the Greek 'kryptos', meaning 'hidden', the same root that gives us 'crypt' (an underground burial chamber) and 'cryptography' (the art of secret writing). In everyday use, 'cryptic' can suggest intriguing mystery or maddening evasiveness: a cryptic crossword clue delights solvers with its layered wordplay, while a friend's cryptic reply may leave you anxious about what went unsaid. The word is especially associated with British-style cryptic crosswords, a puzzle tradition dating to the 1920s. Biologists also use 'cryptic' in technical senses, describing camouflage that hides animals from view or species so alike they are hard to tell apart. Its closest synonyms include 'mysterious', 'enigmatic', and 'puzzling'.
Mysterious, obscure, or deliberately ambiguous in meaning; requiring interpretation to be understood.
"The oracle's cryptic prophecy left the king more worried than before."
Often used of messages, remarks, smiles, and answers that withhold their full meaning.
(Chiefly British) Of or relating to a type of crossword in which each clue is a puzzle of wordplay concealing the answer.
"She spends her Sunday mornings wrestling with the paper's cryptic crossword."
(Biology) Describing coloration, patterning, or form that conceals an organism, or referring to species that are morphologically nearly identical.
"The moth's cryptic markings made it almost invisible against the tree bark."
A specialized scientific sense, most familiar to biologists rather than general readers.
The word 'cryptic' literally means 'fit for hiding' — it comes straight from the Greek kryptos, the same root that gives us crypt, cryptography, and even the chemical element krypton.

Etymology of cryptic
'Cryptic' comes from the Latin 'crypticus', borrowed from the Greek 'kryptikos', meaning 'fit for concealing', which itself derives from 'kryptos', 'hidden'. The Greek verb 'kryptein' meant 'to hide', and this same root produced a whole family of English words, including 'crypt', 'cryptography', 'encrypt', and 'apocryphal'. The word entered English in the early seventeenth century and has carried its sense of hiddenness ever since.

How cryptic is actually used
'Cryptic' can carry either a neutral or a mildly negative connotation depending on context: it may suggest clever subtlety (a cryptic crossword clue) or frustrating evasiveness (a cryptic answer to a direct question). The adverbial form 'cryptically' is far more common than any noun form. In biology, 'cryptic' has a specialized technical sense referring to camouflage or to morphologically indistinguishable species.
Easily confused with cryptic
Both trace back to the Greek root for 'hidden', but apocryphal describes a story or account of doubtful authenticity, whereas cryptic describes something deliberately obscure or puzzling.
