Word Origin & History
early 13c., from L. dirige "direct!" imperative of dirigere "to direct," probably from antiphon Dirige, Domine, Deus meus, in conspectu tuo viam meam, "Direct, O Lord, my God, my way in thy sight," from Psalm v:9, which opened the Matins service in the Office of the Dead. Transferred sense of "any funeral
song" is from c.1500.
