-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).
