An Etymological Dictionary of the German Language/Annotated/Bude
Bude, feminine, ‘booth, stall, shop,’ from Middle High German buode, feminine, ‘hut, tent’; corresponds to Middle English bôþe, ‘taberna,’ English booth; Old Icelandic búð, feminine, ‘dwelling, hut, tent,’ has a different vowel, and is based on the widely diffused root bû-bhû, ‘to dwell, stay.’ By a different derivation English to bui-ld, Anglo-Saxon bold, botl, ‘dwelling,’ Old Frisian bold, Old Icelandic ból, Old Low German bodal, are produced from the same root. So too Old Irish both (bothán), ‘hut,’ from *bu-to, as well as the words discussed under bauen, Lithuanian-Slavonic buda, ‘booth,’ and Bohemian and Silesian Baude, ‘shepherd's hut,’ are borrowed.
