Quenya 

nis-

verb. *to smell sweetly

nís

woman

nís (niss-, as in pl. nissi) noun "woman" _(MR:213. The Etymologies gives _nis (or nissë), pl. nissi: see the stems NDIS-SĒ/SĀ, NI1, NIS (NĒR), VT46:4; compare VT47:33. In Tolkien's Quenya rendering of Hail Mary, the plural nísi occurs instead of nissi; this form is curious, since nísi would be expected to turn into *nízi, *_níri** (VT43:31). VT47:33 suggests that Tolkien at one point considered _niþ- as the older form of the stem, which etymology would solve this problem (since s from older þ does not become z > r). Even so, the MR forms, nís with stem niss-, may be preferred. - Compare †, #nína, nisto, Lindissë.

Lindissë

woman

Lindissë fem.name, perhaps lin- (root of words having to do with song/music) + (n)dissë "woman" (see nís). (UT:210)

nissë

woman

nissë noun "woman" (NDIS-SĒ/SĀ, NI1, NIS, VT47:33); see nís. Note: nissë could apparently also mean "in me", the locative form of the 1st person pronoun ni, q.v.

nissë

noun. woman

woman, female

(2) noun "woman, female" (NI1, INI (NĒR ) ). Not to be confused with as a stressed form of the pronoun ni "I".

nína

woman

#nína (gen.pl. nínaron attested) noun "woman" (VT43:31; this word, as well as some other experimental forms listed in the same source, seem ephemeral: several sources agree that the Quenya word for "woman" is nís, nis [q.v.])

wenci

woman, maiden

wenci ("k") noun, apparently a diminutive form of the stem wēn- "woman, maiden". It is possible that this is meant to be Common Eldarin rather than Quenya; if so the Quenya form would be *wencë (compare nercë "little man") (VT48:18)
