Tiberian Hebrew is the canonical pronunciation of the Hebrew Bible (Tanakh) committed to writing by Masoretic scholars living in the Jewish community of Tiberias in ancient Galilee c. 750–950 CE under the Abbasid Caliphate. They wrote in the form of Tiberian vocalization, which employed diacritics added to the Hebrew letters: vowel signs and consonant diacritics (nequdot) and the so-called accents. These together with the marginal notes masora magna and masora parva make up the Tiberian apparatus.
