Medieval Hebrew
The need to express scientific and philosophical concepts from Classical Greek and Medieval Arabic motivated Medieval Hebrew to borrow terminology and grammar from these other languages, or to coin equivalent terms from existing Hebrew roots, giving rise to a distinct style of philosophical Hebrew.

The Ibn Tibbon family, and especially Samuel ben Judah ibn Tibbon were personally responsible for the creation of much of this form of Hebrew, which they employed in their translations of scientific materials from the Arabic. At that time, original Jewish philosophical and theological works produced in Spain were usually written in Arabic, but as time went on, this form of Hebrew was used for many original compositions as well.
