In the book, "Chasing the Sun" by Richard Cohen, the author gives two possible derivations for the word, "algebra." What seems the most likely? Are there more than two?

goofyThe generally accepted etymology is Arabic "al-jabr". What is the other one you heard?

KallehThe OED says that it originated from Arabic, as goofy says. From the Arabic word, the Italian form was taken. They said the Italian
algèbra eventually became the accepted form, though there is a French from,
algèbre.
Bob would be happy to see that this month the online OED's image is celebrating Mad Hatter's Tea Party.

GeoffNo question that it's Arabic, but Cohen footnotes Martin Isler's book, "Sticks, Stones, and Shadows," which says it derives from a word meaning "...compulsion, as in compelling the unknown 'x' to assume a numerical value. A more colorful notion advanced by some historians is that
algebra means 'putting back into its proper place,' or 'bonesetting.' The bonesetter in
Don Quixote is known as algebrista, but whether because he resets of because he compels, Cervantes never makes clear."

goofyAccording to the OED, الجبر al-jabr is "the redintegration or reunion of broken parts" from the verb جبر jabara "to reunite, redintegrate, consolidate, restore; hence, the surgical treatment of fractures, bone-setting"

KallehThat is interesting about "algebrista" meaning "bonesetter." I looked up "algebrista" in Google and came up with this
site. quote:
algebrista [al-hay-brees’-tah]
noun
1. Algebraist, a person that understands algebra. (m)
2. One who understands setting dislocated members. (Obsolete) (m)
Bone-setter.

GeoffI'm surprised that Proofreader hasn't sugested it as a seaweed breast cover for a mermaid so there, I've done it for him.
But seriously, Cohen seems to think that "bone-setting" is the less likely original meaning. I guess he's got a bone to pick with the OED.

KallehAnd I bet the OED will win...
