Druid A chief priest (Celtic, der, superior; wydd, priest or instructor). In Taliesin we read, Būm gwydd
yngwarth an (at length I became a priest or wydd). It was after this period that the wydds were divided
into two classes, the Der-wydds and the Go-wydds (Druids and Ovidds). Every chief had his druid, and
every chief druid was allowed a guard of thirty men (Strabo). The order was very wealthy. (Not derived
from the Greek drus, an oak.)
