Uin was a great whale according to the early version of the legendarium in The Book of Lost Tales. A host of great whales centering Uin was in the service of Ulmo, being used to drag Tol Eressëa towards Valinor. Uin also pulled Ulmo's fishy cart, and he is said to be the "Primeval Whale" or the "oldest of the Right Whales".
In the Gnomish Lexicon, the word uin means "whale". The original meaning of uin seems to have been "wave". Another Gnomish word for whale was uimoth ("sheep of the waves"), incorporating moth. In Qenya, Uin is given as "a fish, the privemal whale".
