Eldarin

eldarin, elvish

Eldarin adj. derived from Elda: "Eldarin, Elvish" (Silm, ÉLED). Also in the longer form Eldarinwa (pl. Eldarinwë in VT47:14, in the title Eldarinwë leperi ar notessi, "The Eldarin fingers and numerals")

eldarin

noun/adjective. of the Eldar; Elvish (language)

@@@ Helge Fauskanger suggested that Eldarinwa is an extended form of this word as an adjective (QQ/Eldarin). More exactly, I think it is the application of the possessive/adjectival suffix -va to the word Eldarin in its noun-sense = “Elvish language”.
