neldë
cardinal. three
neldë cardinal "three" (SA:neldor, NÉL-ED, VT47:11, VT48:6). Eleni neldë "three stars", archaic elenion neldë = *"of stars three". Genitive "of 3 stars" = elenion neldë (for archaic elenion neldëo) (VT49:45; see 54 regarding neldion as the gen. pl.) Cf. also nelya, neldëa, Neldië.
neldë
cardinal. three, three; [ᴱQ.] four
The Quenya word for “three” derived from √NEL(ED) of the same meaning (VT47/10-11; Ety/NEL).
Conceptual Development: This use of nelde for “three” dates back all the way to Early Qenya Grammar (EQG) of the 1920s (PE14/49, 82). However, in the Qenya Lexicon of the 1910s ᴱQ. nelde was “four”, appearing under the early root ᴱ√NELE “point” and serving as the basis for the word ᴱQ. neldenelqa “square” (QL/65). In this 1910s document, ᴱQ. ole was “three” derived from the early root ᴱ√OLO “tip” (QL/69).
nelya
third
nelya adj. "third" (VT42:25; also neldëa). Pl. Nelyar "Thirds", the original name of the Teleri (or rather the direct Quenya descendant of the original Primitive Quendian name) (WJ:380).
nelya Archaic
ordinal. third
olë
cardinal. three
olë (2) cardinal "three" (LT1:258; in LotR-style Quenya Tolkien replaced this "Qenya" form with neldë)
The usual Quenya word for “third” was neldea as an adjectival form of neldë, along with an alternate (archaic?) form nelya of the same meaning (VT42/25).
Conceptual Development: In the Early Qenya Grammar (EQG) of the 1920s, ᴱQ. nelya was the normal word for “third” (PE14/51, 82).
