The name is Quenya and related to the word falma "wave". The singular term may have been Falmar or Falmaro meaning "wave-er" (cf. ending -ro).[source?] In The Silmarillion the Teleri of Aman are simply known as 'the Teleri', from the Vanyar and Noldor point of view; in fact the Teleri of Aman were properly just the branch of that people.
