What it means
جبر (jabr) is the Persian word for “algebra,” the branch of mathematics dealing with symbols and the rules for manipulating them to solve equations. The word is borrowed from Arabic al-jabr, meaning restoration or the reunion of broken parts, and it appeared in the title of the ninth-century mathematician Muhammad ibn Musa al-Khwarizmi’s landmark work, Kitab al-mukhtasar fi hisab al-jabr wal-muqabala. When this text was translated into Latin in medieval Europe, the term al-jabr was transliterated as algebra, giving the modern European word. In contemporary Persian, جبر (jabr) refers specifically to algebra as a school subject and mathematical discipline, while the word also has an older literary meaning of compulsion or force, used in phrases like جبر و اختیار (jabr o ekhtiyâr, determinism and free will).
How to use it
- جبر از هندسه بیشتر دوست دارم. (Jabr az hendese bishtar dust dâram.) “I like algebra more than geometry.”
- سال دهم جبر خیلی سخت میشه. (Sâl-e dahom jabr kheyli sakht mishe.) “In tenth grade algebra gets very hard.”
- معلم جبر داره معادله توضیح میده. (Mo’allem-e jabr dâre mo’âdele towzih mide.) “The algebra teacher is explaining an equation.”
- جبر خطی تو دانشگاه درس میدن. (Jabr-e khatti tu dâneshgâh dars midan.) “Linear algebra is taught at university.”
Cultural note
Al-Khwarizmi worked at the House of Wisdom in Baghdad in the early ninth century and is considered the father of algebra. His name itself, latinized as Algoritmi, gave rise to the word “algorithm.” Both Persian and Arab scholars claim aspects of his heritage: he wrote in Arabic but his name suggests origins from Khwarazm, a region in present-day Uzbekistan that was historically part of the Iranian cultural sphere. In modern Iran, جبر is a required subject from middle school through the end of secondary education, and success in it is closely tied to university entrance exam scores.
