The Tiberian vocalization marks vowels and stress, makes fine distinctions of consonant quality and length, and serves as punctuation. While the Tiberian system was devised for Tiberian Hebrew, it has become the dominant system for vocalizing all forms of Hebrew and has long since eclipsed the Babylonian and Palestinian vocalization systems.
The sin dot distinguishes between the two values of ש. A dagesh indicates a consonant is geminate or unspirantized, and a raphe indicates spirantization. The mappiq indicates that ה is consonantal, not silent, in syllable-coda position.
