Wulf is a variant of the name Wolf, originating from the Common Germanic *wulfaz, meaning "wolf". It was one of the most prolific elements in early Germanic names, often used as the first or second element in dithematic names. The name's popularity was partly due to the wolf being an animal sacred to Wodanaz, though over time, it became a common suffix in male names, losing its original pagan connotations by the time of Christianisation.
