braffin

A variant form of bargham (“horse collar”), of which other forms include bahfam, barcom, barfing, bariham, barsham, braffam, and (with the morphemes reversed) hamburgh, from Middle English berw-ham, bergham, from Old English beorgan (“shelter”) + ham (“cover”). Or else, a link with Welsh breuant (“throat”), from Proto-Celtic *brāgants, has been suggested.
