na (1) form of the verb "to be", evidently the imperative (or subjunctive): Tolkien stated that na airë would mean "be holy" (VT43:14), and san na (q.v.) must mean "thus be" = "let it be so"; see ná #1 Cf. also the sentence alcar mi tarmenel na Erun "glory in high heaven be to God" (VT44:32/34). Inserted in front of a verb, na expresses a wish: aranielya na tuluva "may thy kingdom come" (ibid).
