Note 242 — TREATISES
Charles Lett Feltoe translation
The derivation from θέειν is proposed by Plato, Cratyl. 397 C: that from θεῖναι by Herod, ii. 52, and of the two the latter is the more likely (√θε) though Curtius suggests a root θες = to pray: see Peile, Introd. to Philology, p. 37 (3rd ed., 1875).
