Proto-North Caucasian: *č̣HǝqwV
Meaning: big
Notes: In PD and PWC there occurred an assimilative deglottalisation *č̣- > *č-. Some doubts are raised by the Lak. form - regularly *č̣aIq- would be expected; maybe pharyngealised *qI was lost in clusters with following class markers (real Lak. forms are č̣aIwu- 1/3, č̣aIru- 2/4 < *č̣aIq-bu-, *č̣aIq-ru- ?).
The PA form suggests that this root could have prefixed class markers in PEC; however, they are absent in all other languages (even in Av.) and may be in this case a PA innovation.
