Proto-North Caucasian: *=ǝ̆qĔ
Meaning: to rise, be high
Notes: As in several other verbal roots, labialisation in PWC is here secondary (probably being a remnant of class prefixation). Otherwise the correspondence is perfectly satisfactory, both phonetically and semantically.
The initial laryngeal in PL (together with PD *ʔ- being derived from *ɦ-) should be probably treated as a historical preverb. Another preverb, *l-, is frequent with this root (cf. the exact parallelism between the Lak. and the PN forms).
There are no certain traces of this root in PTs; cf. perhaps Tsez. iχ-ju 'thick'. It is quite isolated within Tsezian, and may reflect the original adjective 'high' (the correlation 'high' - 'thick' is not unusual in NC languages).
