C&P
//Yes, (corby)N + ONE ('bound'), 'one' being used as you suggest in the sense of 'undivided'. Chambers Thesaurus gives 'bound' as an alternative for 'one' in this sense, although I'm not sure that I could come up with a sentence where the two are interchangeable (as opposed to 'one' and 'united', which can certainly be synonymous).//
