choragus

There are a lot of esoteric words I wouldn’t want to base a puzzle around — like “ultravacua,” “clyping,” “choragi” — which is why the Spelling Bee needs a human touch.

Chorag′ic, pertaining to a choragus.—Choragic monument, a small temple on which were dedicated the tripods given in the Dionysian contests to the victorious chorus.

The chorus came forward, all the singers clad in the Greek costume, at their head as choragus Johannes Diemer, arrayed in diadem and toga.

When it had attained its highest pitch, at a sign from the choragus it ceased—ceased with such suddenness as to impart an impression that was positively uneasy.

Demosthenes was choragus of his tribe, and was wearing the robe of that sacred office at the great festival in the theatre of Dionysus, when Midias struck him on the face.
