Origin
late Middle English: from Italian, Spanish, and medieval Latin, from Arabic aljabr 'the reunion of broken parts', 'bone setting', from jabara 'reunite, restore'. The original sense, 'the surgical treatment of fractures', probably came via Spanish, in which it survives; the mathematical sense comes from the title of a book, ʿilm aljabr wa'lmuḳābala 'the science of restoring what is missing and equating like with like', by the mathematician alḴwārizmī (see algorithm).
