Describe applies primarily to what exists—space, and by extension to what occurs—time, but narrate applies only to the latter: as, to describe a view, a race, or a siege; to narrate an experience or a history. Describe implies often the vividness of personal observation; narrate is more applicable to long series of events. A single narrative may contain many descriptions of separate events.
