Telerin was the language of the Teleri of Aman, a tongue related to both Quenya and Sindarin. It is also called Lindalambe or Lindárin. In Aman the speakers of Telerin outnumbered the speakers of Quenya as did the Teleri outnumber the Vanyar and Noldor. Tolkien stated that from the viewpoint of speakers of Quenya, Telerin was a "closely related language still largely intelligible" (PM:332). However, the phonology of the two languages differed much, Telerin often being more conservative than Quenya.
Finarfin is said to have learnt Telerin.
