BEGA

In the same Dictionary of Volyn Dialect of Ukrainian Language there is a word 'бега' (bega) in the meaning of 'foot'. Sure, it's the source for 'бігати' (bigaty) - 'to run'. Note, that in Georgian 'foot' is 'pehi' which consists of the same consonants as 'bega', but unvoiced. Thus, such Ukrainian words as 'бігати' (bigaty) and 'піхота' (pihota) are more and more likely to be cognates.
