mystère (French)

Where does "mystère" come from?

The French noun 'mystère' is inherited from Middle French 'mystere'[1], which was borrowed from Latin 'mystērium'[1], a borrowing of Ancient Greek 'μῠστήρῐον'[1][3]. The Ancient Greek term traces back to 'μῠ́στης'[2], meaning an initiated one, which ultimately derives from the verb 'μῡ́ω'[2][5] meaning to shut. Over the course of its history, the word shifted from the physical act of shutting to closing one's eyes and finally to someone initiated into secret religious mysteries[5].

• The root verb myo may derive from Proto-Indo-European mewH-ye- meaning to shut, or alternatively from mews-ye-, though the latter root is considered semantically unconvincing. [7]
