Yusuf al-Maghribi

Yūsuf al-Maġribi (Arabic: يوسف المغربي) was a 17th-century lexicographer active in Cairo. He is the first author to treat Egyptian Arabic as a dialect distinct from Classical Arabic, compiling an Egyptian Arabic word list, the Raf` al-'iṣr `an kalām 'ahl miṣr (i.e. "apology of the Egyptian vernacular", literally "the lifting of the burden from the speech of the population of Egypt"), which survives in a unique manuscript kept at St. Petersburg State University. Al-Maghribi's dictionary reflects a wider trend inearly 17th century Ottoman Egypt towards colloquial writing.
