Púca
The origin of the name may have come from the Old Norse term "pook" or "puki", which refers to a "nature spirit". Usage of the term in Ireland, however, may predate the arrival of Norse settlers.
In Germanic languages, such as Frisian or English, this became "pucel", "pook" or "puck". The name of the pooka may also come from the Irish word "poc", meaning a male goat, a form the creature is often said to take.
