COMMENT: One of a series of roots sounding like *KVNTV / *TVNKV and meaning 'drop, spot' (see also *ṭVnḳǝ̆,*ḳwɨmṭV,*ḳanṭV). All of them are clearly expressive and tend to contaminate with each other. The root *ṭHänḳŏ, however, is the only one having parallels in WC. See Abdokov 1983, 103.
Cauc. > Osset. (Dig.) ṭink,ṭing 'drop', see Abayev 1979, 356.
