-mma

our

-mma "our", 1st person dual exlusive possessive ending: *"my and one others" (VT49:16). At an earlier conceptual phase, Tolkien apparently intended the same ending to be plural inclusive "our" (VT49:55, RS:324), cf. Mélamarimma "Our Home" (q.v.) In the latter word, Tolkien slips in i as a connecting vowel before this ending; elsewhere he used e, as in Átaremma "our Father" (see atar).
