sibylline

Mysteriously predicting futures

Sibylline means mysteriously prophetic or obscurely oracular, like the utterances of the ancient sibyls—women believed to channel divine prophecy.

The word describes statements that seem to foretell the future but in cryptic, ambiguous terms: Her sibylline warnings proved accurate only in hindsight.

Extended use covers anything darkly enigmatic or deliberately obscure: a sibylline smile, sibylline pronouncements from the chairman.
