After the Talmud, various regional literary dialects of Medieval Hebrew evolved. The most important is Tiberian Hebrew or Masoretic Hebrew, a local dialect of Tiberias in Galilee that became the standard for vocalizing the Hebrew Bible and thus still influences all other regional dialects of Hebrew. This Tiberian Hebrew from the 7th to 10th century CE is sometimes called "Biblical Hebrew" because it is used to pronounce the Hebrew Bible; however properly it should be distinguished from the historical Biblical Hebrew of the 6th century BCE, whose original pronunciation must be reconstructed.
Tiberian Hebrew incorporates the remarkable scholarship of the Masoretes (from masoret meaning "tradition"), who added vowel points and grammar points to the Hebrew letters to preserve much earlier features of Hebrew, for use in chanting the Hebrew Bible. The Masoretes inherited a biblical text whose letters were considered too sacred to be altered, so their markings were in the form of pointing in and around the letters. The Syriac script, precursor to the Arabic script, also developed vowel pointing systems around this time. The Aleppo Codex, a Hebrew Bible with the Masoretic pointing, was written in the 10th century likely in Tiberias and survives to this day. It is perhaps the most important Hebrew manuscript in existence.Free Quote
In the Golden age of Jewish culture in the Iberian Peninsula important work was done by grammarians in explaining the grammar and vocabulary of Biblical Hebrew; much of this was based on the work of the grammarians of Classical Arabic. Important Hebrew grammarians were Judah ben David Hayyuj and Jonah ibn Janah. A great deal of poetry was written, by poets such as Dunash ben Labrat, Solomon ibn Gabirol, Judah ha-Levi and the two Ibn Ezras, in a "purified" Hebrew based on the work of these grammarians, and in Arabic quantitative metres. This literary Hebrew was later used by Italian Jewish poets.
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.
Hebrew was also used as a language of communication among Jews from different countries, particularly for the purpose of international trade.
