COMMENTS:Trask (1995, 1997) discusses whether *burar or *bular is original, noting Michelena (1961) suggested *burar. 'chest' appears to be the original meaning ... also used for 'female breast' ... specialized in this sense in Gipuzkoan" (Trask 1997). A development of *burha-r̄ > *buɫha-r̄ is also possible in this model.
