Proto-North Caucasian: *č̣HwīlV (~ ć̣-, -ē-, -ɨ̄-)
Meaning: a small bird
Notes: An Av.-And.-Lak. isogloss; the comparison seems plausible both phonetically and semantically. We can also mention Ud. aIl 'partridge': since all weak affricates were lost in Ud., this form can go back to PL *č̣ʷVIl, and may be related to the PA and Lak. forms.
