Adjectival form of Teler, the third tribe of Elves, also used as a name for their language (UT/229; WJ/21), a combination of their tribal name with the language/adjective suffix -rin.
Conceptual Development: The similar adjectival forms ᴱQ. Telellin and ᴱQ. Telerin appeared in Tolkien’s earliest writings (LT1A/Telelli), though at this stage they referred to other groups of Elves (see the entry on Teler). By the 1930s, however, ᴹQ. Telerin referred to the third tribe and its language (Ety/TELES; LR/171; PE18/26).
Telerin adj. "Telerian" (TELES). Also telerinwa.
