Proto-North Caucasian: *ʕapālq̇wĔ(~ *ɦ-)
Meaning: burdock; leaf
Notes: In Av. the voiced -b- is obviously secondary (a normal result of *-p- > *-ṗ- /before a glottalised stop/ > -b-). Otherwise the correspondences are regular (*-l- disappearing in cluster in Av. and yielding nasalisation in PTs). The PD form probably comes from *hepq̇ul(i) with reduction of the medial vowel and cluster simplification.
There are some doubts whether the WC form belongs here (in this case a usual delabialisation *-Gʷ- > *-G- after a labial should be assumed) or to another root (*panG_VlhV 'leaf; bark' q.v.) - both possibilities should be considered.
