English: nickname for a man with some fancied resemblance to a he-goat (Old English bucc(a)) or a male deer (Old English bucc). Old English Bucc(a) is found as a personal name, as is Old Norse Bukkr. Names such as Walter le Buk (Somerset 1243) are clearly nicknames. English: topographic name for someone who lived near a prominent beech tree, such as Peter atte Buk (Suffolk 1327), from Middle English buk ‘beech’ (from Old English boc). German: from a personal name, a short form of Burckhard (see Burkhart). North German and Danish: nickname for a fat man, from Middle Low German buk ‘belly’. Compare Bauch. German: variant of Bock. German: variant of Puck in the sense ‘defiant’, ‘spiteful’, or ‘stubborn’. German: topographic name from a field name, Buck ‘hill’.
