lúva

noun. bow (in forming tengwar), bight, bend, curve

A word Tolkien used to describe the “bow” of tengwar in Appendix E of The Lord of the Rings (LotR/1118). Elsewhere he indicated it was a general word for a “bend, bow, bight, curve” (PE17/122, 168). Tolkien variously derived this word from the roots √LUB or √(N)DUB; see those entries for discussion. He also specified that lúva was not a bow for shooting (PE17/122), as opposed to [ᴹQ.] qinga given elsewhere as a shooting bow (Ety/KWIG).
