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. This is used in the translations made by the Ibn Tibbon family. (Original Jewish philosophical works were usually written in Arabic.) Another important influence was Maimonides, who developed a simple style based on Mishnaic Hebrew for use in his law code, the Mishneh Torah. Subsequent rabbinic literature is written in a blend between this style and the Aramaized Rabbinic Hebrew of the Talmud.
