§ Of the Coming of the Elves and the Captivity of Melkor The Silmarillion

The greatest host came last, and they are named the Teleri, for they tarried on the road, and were not wholly of a mind to pass from the dusk to the light of Valinor. In water they had great delight, and those that came at last to the western shores were enamoured of the sea. The Sea-elves therefore they became in the land of Aman, the Falmari, for they made music beside the breaking waves. Two lords they had, for their numbers were great: Elwë Singollo (which signifies Greymantle) and Olwë his brother.
