Origin

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).

  • Bone-setting does not seem to have much to do with mathematics, but there is a connection in the word algebra. It comes from the Arabic al-jabr ‘the reunion of broken parts’, used specifically to refer to the surgical treatment of fractures and to bone-setting. Algebra was used in this meaning in English in the 16th century. The mathematical sense comes from the title of a 9th-century Arabic book ilm al-jabr wa'l-mukabala, ‘the science of restoring what is missing and equating like with like’, written by the mathematician al-Kwarizmi (c.790–c.840).
