-nna "to, at, upon", allative ending, originating from -na "to" with fortified n, VT49:14. Attested in cilyanna, coraryanna, Endorenna, Elendilenna, númenórenna, parma-restalyanna, rénna, senna, tielyanna, q.v. If a noun ends in -n already, the ending -nna merges with it, as in Amanna, formenna, Elenna, númenna, rómenna as the allative forms of Aman, formen, elen, númen, rómen (q.v.). Plural -nnar in mannar, valannar, q.v.

-n (1) dative ending, originating as a reduced form of -nă "to", related to the allative ending -nna (VT49:14). Attested in nin, men, ten, enyalien, Erun, airefëan, tárin, yondon (q.v.) and also added to the English name Elaine (Elainen) in a book dedication to Elaine Griffiths (VT49:40). The longer dative ending -na is also attested in connection with some pronouns, such as sena, téna, véna (q.v.), also in the noun mariéna from márië "goodness" (PE17:59). Pl. -in (as in hínin, see hína), partitive pl. -lin, dual -nt (Plotz). The preposition ana (#1) is said to be used "when purely dative formula is required" (PE17:147), perhaps meaning that it can replace the dative ending, e.g. *ana Eru instead of Erun for "to God". In some of Tolkiens earlier material, the ending -n (or -en) expressed genitive rather than dative, but he later decided that the genitive ending was to be -o (cf. such a revision as Yénië Valinóren becoming Yénië Valinórëo, MR:200).
ana
to
ana (1) prep. "to" (VT49:35), "as preposition _ana _is used when purely _dative formula is required" (PE17:147), perhaps meaning that the preposition ana can be used instead of the dative ending -n (#1, q.v.) Also as prefix: ana- "to, towards" (NĀ1); an (q.v.) is used with this meaning in one source (PE17:127)_
na
to, towards
na (2) prep. "to, towards", possibly obsoleted by #1 above; for clarity writers may use the synonym ana instead (NĀ1). Originally, Tolkien glossed na as "at, by, near"; the new meaning entered together with the synonyms an, ana (VT45:36).
númen noun "west, the way of the sunset" (SA:andúnë, cf. NDŪ, MEN; capitalized Númen under SA:men and in CO), "going down, occudent" (Letters:361), also name of tengwa #17 _(Appendix E). _According to VT45:38, the word is actually cited as "nú-men" in Tolkien's Etymologies manuscript. Allative númenna "Westward" (LR:47, SD:310, VT49:20, capitalized Númenna, VT49:22; numenna with a short u, VT49:23); adj. númenquerna "turned westward" (VT49:18, 20). See also númenyaron, númessier. - In the pre-classical Tengwar system presupposed in the Etymologies, "nú-men" was intended as the name of tengwa #21, to which letter Tolkien at this stage assigned the value n (VT45:38). However, this tengwa was later given the Quenya value r instead and was renamed órë.
