booth: [12] In common with a wide range of other English words, including bower and the -bour of neighbour, booth comes ultimately from the Germanic base *bū- ‘dwell’. From this source came the East Norse verb bóa ‘dwell’ (whose present participle produced English bond and the -band of husband); addition of the suffix -th produced the unrecorded noun bóth. ‘dwelling’, which came into Middle English as bōth. => be, boor, bower, husband, neighbour[booth etymology, booth origin, 英语词源]
