Proto-North Caucasian: *č̣_wɦĕli ( ~ -ʕ-, -ɫ-)
Meaning: a k. of foliage tree
Notes: The Av. word reflects a suffix *-di (*č̣_wɦĕldi), common for many plant-names. One feels tempted to compare PWC > PAK *(p)c:aLǝ 'willow' (Ad. pceLǝ, Kab. ʒaL), but there are significant phonetic obstacles (PAK *c: can go back to PWC *č:, but we would rather expect *č̣́ʷ- in Anlaut). Thus the root so far remains an Av.-Lezg. isogloss.
