Elu Thingol is the King of Doriath and High King of the Sindar. Thingol was the Sindarin form of an epithet of Elu. Elu comes from Elwë, "Star-man" (man in the sense male, not human). Thingol comes from sindacollo, "grey cloak". The Quenya form of the same name is Elwë Singollo, the latter again meaning "Graycloak". He is the brother of Olwë, who is the King of Alqualonde and High King of the Teleri of Aman. He was also a good friend of Finwë, High King of the Ñoldor. He may have had a second brother, Elmo.
