man

who

man pron. "who" (Nam, RGEO:67, FS, LR:59, Markirya, MC:213, 214); cf. PM:357 note 18, where a reference is made to the Eldarin interrogative element ma, man). However, man is translated "what" in LR:59: man-ië? "what is it?" (LR:59; the stative-verb suffix -_ is hardly valid in LotR-style Quenya) _Either Tolkien later adjusted the meaning of the word, or man covers both "who" and "what". Cf. also mana, manen.
