Late Middle English: from Italian, Spanish, and medieval Latin, from Arabic al-jabr 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, ‘ilm al-jabr wa'l-muqābala the science of restoring what is missing and equating like with like, by the mathematician al-Ḵwārizmī (see algorithm).
