between
imbë (1) prep "between" (Nam, RGEO:67, VT47:11, PE17:92). This is "between" referring to a gap, space, barrier, or anything intervening between two other things, like or unlike one another (compare enel). The pluralized form imbi implies "among" of several things (ancalima imbi eleni "brightest among stars"); "in the sense 'among' before plurals [imbë] is usually pluralized > imbi even when a plural noun follows". As pointed out by Patrick Wynne, imbi may also be used in the sense of "between" before two singular nouns connected by "and" (as in the example imbi Menel Cemenyë "between heaven and earth"), whereas imbë is used before dual forms, as in the examples imbë siryat "between two rivers", imbë met "between us". Elided imb' in the phrase imb' illi "among all" (VT47:11, 30). A dual form imbit is also mentioned, used to express "in absolute form the sense 'between two things' when these are not named" (apparently meaning that imbit expresses *"between them" referring to two entities, with no noun following) (VT47:30, PE17:92)

mitta
preposition/adverb. between, [ᴹQ.] inwards, into, [ᴱQ.] in; [Q.] between
A derivative of √MI “in” with various meanings throughout Tolkien’s life. It seems to mean “in” within the name Mittalmar “Inlands” from the mid-1960s. In Quenya prayers of the 1950s, it was briefly used for “among” before being revised to mika (VT43/27-28), and was glossed “between” in accompanying etymological notes (VT43/30). In The Etymologies of the 1930s, ᴹQ. mitta or minta was glossed “inwards, [?]into” [the second gloss is difficult to read] under the root ᴹ√MI “inside” (EtyAC/MI). In the Qenya Lexicon of the 1910s ,ᴱQ. mitta was glossed “in, into, inwards” under the early root ᴱ√MĪ (QL/61).
Neo-Quenya: For purposes of Neo-Quenya, I would use mitta as a preposition or adverb meaning “inwards, into”, and would assume the 1950s meaning “between” was transient and abandoned.

nandë
valley
nandë (1) noun "valley" in Laurenandë (UT:253), elided nand in the name Nand Ondoluncava (k") "Stonewain Valley" (PE17:28). Possibly the complete word is here meant to be the variant nando (PE17:80), as suggested by the alternative form Ondoluncanan(do) ("k") "Stonewain Valley". Also nan, nand- noun "valley" (Letters:308); Nan-Tasarion "Vale of Willows" (LotR2:III ch. 4) (Note that this and the next nandë would be spelt differently in Tengwar writing, and originally they were also pronounced differently, since nandë "harp" was ñandë in First Age Quenya.)
