Mystery

/ˈmɪstəri/noun

Something unexplained or unexplainable; also a story built around a crime to be solved.

The Greek roots

μυστήριον
mystḗrion
secret rite, initiation

Literally: secret rite

The story of the word

A mystḗrion was a rite you were initiated into, and a mýstēs was the initiate, from mýō, to close the lips or the eyes. The Eleusinian Mysteries ran for something like two thousand years and not one participant left a record of what happened inside, which is an extraordinary result for a secret shared by thousands. The detective sense is nineteenth century. The mystery in mystery play is a different word entirely, from Latin ministerium, a craft or trade guild.
