Forms:

α. Middle English– algebra, late Middle English algabra.

β. 1500s–1600s algeber, 1600s algebre.

γ. 1500s algiebar.

Origin: A borrowing from Latin. Etymon: Latin algebra.

Etymology: < post-classical Latin algebra algebraic computation (12th or 13th cent.), surgical treatment of fractures (c1300) < Arabic al-jabr < al the + jabr restoration (of anything which is missing, lost, out of place, or lacking), reunion of broken parts, (hence specifically) surgical treatment of fractures < jabara to restore, to reunite, (hence specifically in a medical context) to set broken bones.The Arabic term al-jabr probably originally referred specifically to the method of solving quadratic equations by completing the square (see to complete the square at complete v. Additions). The term achieved currency through the title of the 9th-cent. mathematical treatise by al-Ḵwārizmī, al-kitāb al-muḵtaṣar fī ḥisāb al-jabr wal-muqābala ‘The Concise Book on Calculation by Restoration and Compensation’. This work was partially translated into Latin by the British scholar Robert of Chester (fl. 12th cent.); shortly afterwards, the Italian scholar Gerard of Cremona (fl. late 12th cent.) made a second translation of it, De jebra et almucabola. For biographical information on al-Ḵwārizmī, see algorism n. The modern Arabic term denoting the branch of mathematics is ʿilm al-jabr . Compare Middle French, French †algebre (now algèbre ) (a1376 in an apparently isolated attestation, subsequently from 1554; 1546 in Rabelais as algebra , all denoting the branch of mathematics; 1611 in Cotgrave in an isolated attestation denoting the surgical treatment of fractures), Spanish algebra (a1450 denoting the surgical treatment of fractures, 1552 denoting the branch of mathematics), Portuguese álgebra (1519 denoting the branch of mathematics; 1712 in medical use), Italian algebra (1598 in Florio denoting the surgical treatment of fractures, 1606 denoting the branch of mathematics); also Middle Dutch, Dutch algebra (1460 in an isolated attestation denoting the surgical treatment of fractures, 1612 denoting the branch of mathematics), German Algebra (1460 in puech algebra un almalcobula lit. ‘book of algebra and almacabala’ as the title of a translation of al-Ḵwārizmī's mathematical treatise; 1489 as algobre , denoting the branch of mathematics). Compare almacabala n. In β. forms probably after Middle French algebre; in the form algeber, the word was associated by early authors with Geber, the pseudonym of a 13th-cent. European alchemist (now called Pseudo-Geber) who wrote a number of treatises using the name of the 8th-cent. Arabic alchemist Jābir b. Ḥayyān (in Latinized form, Geber ). In γ. forms apparently after the ulterior Arabic etymon. The position of the stress probably varied in early use (compare the French parallel, which shows penultimate stress). The current first-syllable stress, exemplified e.g. in quot. 1663 at sense 2a, is attested from at least c1600.

1. Surgical treatment of a fractured or dislocated bone. Also (as a count noun): a fracture or dislocation. Now historical and rare.

2. Mathematics.

a. As a mass noun: (originally) the branch of mathematics in which letters are used to represent numbers in formulae and equations; (in later use more widely) that in which symbols are used to represent quantities, relations, operations, and other concepts, and operations may be applied only a finite number of times.abstract, Boolean, matrix, quadruple, tensor algebra, etc.: see the first element.
