Notes: Reconstructed for the PEC level. The meaning 'drop' in some languages (Kar., Lak., Rut.) is probably a result of partial contamination with another similar PEC root, *ṭHänḳŏ q.v.
An EC source is probable for Georg. ḳwinṭali 'pimple', Osset. ḳʷɨdīlɨ / gudeli 'wart' (see Abayev 1958, 646-7: Osset.-Georg.).
