From Tolkien Gateway
Lanthir Lamath, the "Waterfall of Echoing Voices" was the shimmering, glittering waterfall that ran beside the house of Dior Eluchíl in Ossiriand, probably part of the stream of the River Adurant. Lanthir Lamath was most famous for inspiring the name of Dior's daughter Elwing, whose name - meaning 'Star-spray' - was inspired by the falling water on the night of stars when she was born.
Lanthir Lamath is Sindarin for "Waterfall of Echoing Voices", from lamthir ("waterfall") + plural lam ("echo").
