Medieval Hebrew refers to the form of the Hebrew language used during the Middle Ages, roughly from the 9th to the 18th centuries. This period saw the development of Hebrew literature, including poetry, philosophy, and religious texts. Notable figures, such as Maimonides and Judah Halevi, contributed significantly to Hebrew writing during this time. The language evolved from Biblical Hebrew and incorporated elements from surrounding languages, such as Arabic and Latin. Medieval Hebrew was used by Jewish communities across Europe, North Africa, and the Middle East, serving as a vital means of communication and cultural expression among Jews.
