ABRAHAM HA-BAVLI (apparently early 11th century), grammarian. Abraham ha-Bavli is mentioned by Abraham Ibn Ezra and Jacob b. Meir (Rabbenu Tam). His Sefer ha-Shorashim ("Book of Roots"), only part of which has been published (1863), deals with roots of one to four letters, interchanges in the order of the root letters, homonymic roots, and an elision or interchange of one of the root letters for another letter. Some scholars mistakenly identify him with the Karaite grammarian David b. Abraham *Alfasi.
