anda adj. "long" (ÁNAD/ANDA), "far" (PE17:90).In Andafangar noun "Longbeards", one of the tribes of the Dwarves (= Khuzdul Sigin-tarâg and Sindarin Anfangrim) (PM:320). Compare Andafalassë, #andamacil, andamunda, andanéya, andatehta, Anduinë. Apparently derived from the adj. anda is andavë "long" as adverb ("at great length", PE17:102), suggesting that the ending -vë can be used to derive adverbs from adjectives (LotR3:VI ch. 4, translated in Letters:308)
