neltil

noun. triangle

A word for “triangle” in The Etymologies of the 1930s, a combination of ᴹ√NEL “three” and ᴹ√TIL “point” (Ety/NEL, TIL).

Conceptual Development: The Qenya Lexicon of the 1910s had ᴱQ. neldenelqa “square, quadrilateral” (lit. “four-cornered”), since in this document ᴱQ. nelde meant “four” (QL/65).
