óma noun "voice" (OM), "voice, resonance of the vocal chords" (VT39:16), "voice /vowel" _(PE17:138, where it is said that the root _OM refers to "drawn-out" sounds; contrast tomba, q.v.). With pronominal suffix #ómarya "his/her voice", genitive ómaryo "of his/her voice" (Nam, RGEO:67). Instrumental pl. ómainen "with voices" _(WJ:391). Adj. ómalóra "voiceless" (VT45:28)_. The term óma is closely associated with vowels, see óma-tengwë, ómëa; cf. also the compounds ómataina "vocalic extension", the addition to the base a final vowel identical to the stem-vowel (WJ:371, 417; also called ómataima, VT42:24, 25), ómatehtar "vowel-signs", signs used for vowels (usually called simply tehtar, but the latter term strictly includes all kinds of diacritics, not just the vowel-signs) (WJ:396)
