title_body: How many dialects of Tolkien's Elvish are there? I've seen several variations of Tolkien's Elvish around, with different names, such as Sindarin and Q(u)enya.
  
  How many dialects of Tolkien's Elvish are there, and how do they differ from one another?
upvoted_answer: In this article, it is mentioned:
  
  
  Primitive Quendian (language of the Elves in Cuiviénen)
  Avarin
  Various Avarin languages (some later merged with Nandorin)
  Common Eldarin (the early language of all the Eldar)
  Quenya (the language of the Ñoldor and the Vanyar)
  Quendya (also Vanyarin Quenya) (daily tongue of the Vanyar: closest to archaic Quenya)
  Ñoldorin Quenya (also Exilic Quenya) (the "Elven Latin" of Middle-earth)
  Common Telerin (the early language of all the Lindar)
  Telerin (the language of the Teleri who reached the Undying Lands)
  Nandorin (languages of the Nandor — some were influenced by Avarin)
  Original language of Greenwood the Great
  Original language of Lórinand
  Sindarin (language of the Sindar)
  Doriathrin (dialect of Doriath)
  Falathrin (dialect of the Falas and Nargothrond)
  North Sindarin (dialects of Dorthonion and Hithlum)
  
  
  So a good many dialects exist. However, we cannot exactly count how many there are, because it mentions "various" and we don't know whether there is a hierarchy of languages that have branched off somewhere else.  However, we can confirm there are at least 17 dialects of the Elvish.
