Origin

Etymology tree Arabic ال (al-) Old Persian 𐎢𐎺𐎠𐎼𐏀𐎷𐎡𐏁 (u-v-a-r-z-mi-i-š) Classical Persian خْوَارَزْم (xwārazm)bor.

Middle English algorisme English algorism ▲ English arithmo-influ. English algorithm From Middle English algorisme, augrym, from Anglo-Norman algorisme, augrim, from Medieval Latin algorismus, from Arabic الخَوَارِزْمِيّ (al-ḵawārizmiyy), the nisba of Persian mathematician Muḥammad ibn Mūsā al-Khwārizmī and a toponymic name meaning "person from Chorasmia". The spelling change (-s- > -th-) was influenced by unrelated Ancient Greek ἀριθμός (arithmós) (whence English arithmo-).
