Varieties of Arabic
There are many varieties of Arabic (also called dialects of Arabic or vernacular languages) in existence. Arabic is a Semitic language within the Afroasiatic family that originated on the Arabian Peninsula. It is classified as a macrolanguage comprising 30 modern varieties, including its standard form. The largest divisions occur between the spoken languages of different regions. Some varieties of Arabic in North Africa, for example, are not easily comprehensible to an Arabic speaker from the Levant or the Persian Gulf. Within these broad regions further and considerable geographic distinctions exist, within countries, across country borders, even between cities and villages.
Hejazi Arabic
Hejazi Arabic verbs, as with the verbs in other Semitic languages, and the entire vocabulary in those languages, are based on a set of three, four also five consonants (but mainly three consonants) called a root ("triliteral" or "quadriliteral" according to the number of consonants). The root communicates the basic meaning of the verb, e.g. ' 'to write', ' 'to eat'. Changes to the vowels in between the consonants, along with prefixes or suffixes, specify grammatical functions such as :
Hejazi Has a single indicative present verb mood instead of the three Classical Arabic present verb moods (indicative رفع, subjunctive نصب, jussive ), it also includes present progressive tense which was not part of the Classical Arabic grammar, and has a two grammatical number in verbs (Singular and Plural) instead of the Classical (Singular, Dual and Plural).
