Notes: In most subgroups the word could be borrowed from Arabic baṭṭ 'duck' (since there are, of course, no domestic waterfowl in most modern NC communities); however, some phonetic peculiarities (especially nasalisation in Tsez.) make us think of the possibility of PEC reconstruction. Besides Arabic the word is known also in Georgian (baṭi 'goose'), where it may well be borrowed (either from Nakh or also from Semitic). The problem requires a further investigation.
