Naffarin is a language created in the 1910s by J.R.R. Tolkien. Naffarin incorporated some of the latest stages of Nevbosh. This language was inspired by Latin and Spanish.
In his lecture 'A Secret Vice', Tolkien mentions one Naffarin sentence to illustrate, but there is no translation: O Naffarínos cutá vu navru cangor luttos ca vúna tiéranar, dana maga tíer ce vru encá vún' farta once ya merúta vúna maxt' amámen.
Based on the above phrase, Helge Fauskanger noted that Naffarin has several elements in style and structure that might resemble future Elvish (in 1915 Tolkien would start writing the Qenya Lexicon).
