Arabic is a Semitic language, closely related to the Hebrew language. Many dialects are spoken in modern Arabic states such as Egypt, Lebanon, and Morocco, but all of these countries use Modern Standard Arabic for printed media. Its function however is different from Western standard languages: it is mainly the language of the Quran (in its Classical form), and is not spoken in everyday life. Consequently, prestigious vernacular varieties have some of the functions that standard languages have in Western countries (see Chambers, Sociolinguistic Theory). Arabic is the language of Islam, but is also spoken by Arab Christians and Oriental Jews.
The Arabic alphabet derives from the Aramaic.
Standard Arabic has only three vowels, in long and short variants, namely /i, a, u/. Naturally, there is quite some allophony.
Voiceless plosives: /t/, /t'/, /k/, /q/, /?/
Voiced plosives: /b/, /d/, /d'/, /dZ/ (/dZ/ is /g/ for some speakers, i.e. a plosive)
voiceless fricatives: /f/, /T/, /s/, /s'/, /S/, /x/, /X\/, /h/
voiced fricatives: /D/, /z/, /z'/, /G/, /?\/
Nasals: /m/, /n/
Laterals: /l/ ([l'] only in /?alla:h/, the name of God, i.e. Allah)
Vibrant: /r/
Semi-vowels: /w/, /j/
/'/ is used to indicate velarization and pharyngalization (=emphatic consonants; usually transcribed as dotted consonants). The other symbols are SAMPA.
Vowels and dipthongs can be (phonologically) short or long.
