While many languages have numerous dialects that differ in phonology, the contemporary spoken Arabic language is more properly described as a continuum of varieties. This article deals primarily with Modern Standard Arabic (MSA), which is the standard variety shared by educated speakers throughout Arabic-speaking regions. MSA is used in writing in formal print media and orally in newscasts, speeches and formal declarations of numerous types.
Modern Standard Arabic has 28 consonant phonemes and 6 vowel phonemes (8 vowels in most modern dialects). All phonemes contrast between "emphatic" (uvularized) consonants and non-emphatic ones. Some of these phonemes have coalesced in the various modern dialects, while new phonemes have been introduced through borrowing or phonemic splits. A "phonemic quality of length" applies to consonants as well as vowels.
