Alteration of Middle English algorisme, from Old French & Medieval Latin; Old French, from Medieval Latin algorismus, from Arabic al-khuwārizmi, from al-Khwārizmī fl a.d. 825 Islamic mathematician
First Known Use: 1926


Al-Khwārizmī, Persian astronomer and mathematician, wrote a treatise in Arabic in 825 AD, On Calculation with Hindu Numerals. (See algorism). It was translated into Latin in the 12th century as Algoritmi de numero Indorum (al-Daffa 1977), which title was likely intended to mean "[Book by] Algoritmus on the numbers of the Indians", where "Algoritmi" was the translator's rendition of the author's name in the genitive case; but people misunderstanding the title treated Algoritmi as a Latin plural and this led to the word "algorithm" (Latin algorismus) coming to mean "calculation method". The intrusive "th" is most likely due to a false cognate with the Greek αριθμος (arithmos) meaning "number".
