Scottish rhyme
Although there are a number of faeries from liturature which had specific names (Oberon, Titania, Puck, Robin Goodfellow, Meg etc.) most faeries in myths and legends were referred to by some local name such as pisky, boggart or trow . The reason for this is the fact that most faeries will not reveal their true names, but only a nickname. The power which ones true name holds over them is well known to wizards and many savage and superstitious peoples as well as to faeries. There are many tales where a faerie holds some threat over a human, and the only escape is by finding out the faerie's true name, which they often reveal unknowingly while singing to themselves unobserved (so they thought) by anyone. The most familiar of these stories is the tale of Rumpelstilzchen.
