Vowel-point definitions

Any of a number of diacritical marks written above or below consonants to indicate a preceding or following vowel in languages that are usually written without vowel letters, as in Hebrew and Arabic.

In certain languages whose written form normally consists only of consonants, as Hebrew, a diacritical mark accompanying a consonant (to indicate the following vowel sound) or a neutral letter (to indicate esp. an initial vowel sound)
