nertë

cardinal. nine

The Quenya word for “nine” derived from the root √NETER of the same meaning (PE17/95; VT42/26; VT48/6; Ety/NÉTER).

Conceptual Development: The Early Qenya Grammar (EQG) of the 1920s had ᴱQ. {huo >>} hue “nine” (PE14/49, 82), and the Qenya Lexicon of the 1910s had ᴱQ. olme(t) “nine” under the early root ᴱ√OLO “tip” (QL/69).

nettë

girl, daughter

nettë (stem *netti-, given the primitive form listed in VT47:17) noun "girl, daughter" (but also "sister", see below), also used as a play-name of the "fourth finger" or "fourth toe" (VT47:10, VT48:6), in two-hand play also used for the numeral "nine" (nettë is conceived as being related to nertë, q.v.) Nettë is also defined as "sister" or "girl approaching the adult" (VT47:16, VT49:25), "girl/daughter" (VT47:15-16); it may be that "sister" was Tolkien's final decision on the meaning (VT48:4, 22) - The related word nésa seems like a less ambiguous translation of "sister".
