Query: How many dialects of Arabic are there?
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.[1] 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.
The case of Iraq also illustrates how there can be significant differences in how Arabic is spoken on the basis of religion. (Note that the study referred to here was conducted before the Iraq War.) In Baghdad, there are significant linguistic differences between Arabic Christian and Muslim inhabitants of the city. The Christians of Baghdad are a well-established community, and their dialect has evolved from the sedentary vernacular of urban medieval Iraq. The typical Muslim dialect of Baghdad is a more recent arrival in the city and comes from Bedouin speech instead. In Baghdad, as elsewhere in the Arab world, the various communities share MSA as a prestige dialect, but the Muslim colloquial dialect is associated with power and money, given that that community is the more dominant. Therefore, the Christian population of the city learns to use the Muslim dialect in more formal situations, for example, when a Christian school teacher is trying to call students in the class to order.[17]
Sanʽani syntax differs from other Arabic dialects in a number of ways. It is one of few remaining Arabic dialects to retain the "mā af‘al" exclamatory sentence type with the meaning "how (adjective)". For instance, "mā ajmal", is used to mean "how beautiful", from the adjective "jamīl", meaning "beautiful"; a construction it shares with Libyan Arabic and Levantine Arabic.
Like most Modern South Arabian dialect speakers in Oman and Yemen, many Shehri speakers are bilingual in local dialects of Arabic especially the Dhofari dialect. In addition, it is primarily a spoken language, and there is no tradition of writing or publishing in the language. Pressure from Arabic has forced many changes in the language, so much so that young speakers use noticeably different grammar.
Baghdad Jewish Arabic () is the Arabic dialect spoken by the Jews of Baghdad and other towns of Southern Iraq. This dialect differs from the dialect spoken by the Jews in Northern Iraq, such as Mosul and 'Ana. The Baghdadi and Northern dialects may be regarded as subvarieties of Judeo-Iraqi Arabic. As with most Judeo-Arab communities, there are likely to be few, if any, speakers of the Judeo-Iraqi Arabic dialects who still reside within Iraq. Rather these dialects have been maintained or are facing critical endangerment within respective Judeo-Iraqi diasporas, namely those of Israel and the United States. In 2014, the film "Farewell Baghdad" (Arabic: مطير الحمام; Hebrew: מפריח היונים, lit. "The Dove Flyer"), which is performed mostly in Jewish Baghdadi Arabic dialect, became the first film to be almost completely performed in Judeo-Iraqi Arabic.
While some may speak the formal Literary Arabic, many Syrians speak Syrian Arabic, a dialect which belongs to the Levantine Arabic family of dialects. There are also sub-dialects in Syrian Arabic; for example, people from Aleppo have a distinct and distinguishable accent, one that differs considerably from that of people from Homs or Al-Hasakah. Syrians can usually comprehend and understand the dialects of most Arabs, especially those who speak any form of Levantine Arabic.
As part of a dialect continuum, Tunisian merges into Algerian Arabic and Libyan Arabic at the borders of the country. Tunisian Arabic's morphology, syntax, pronunciation, and vocabulary are considerably different from Modern Standard Arabic or Classical Arabic. Like other Maghrebi dialects, it has a vocabulary that is mostly Arabic with a significant Berber, Latin and possibly Neo-Punic substratum. However, Tunisian has also many loanwords from French, Turkish, Italian and the languages of Spain.
The phonological system of Hassānīya is both very innovative and very conservative. All phonemes of Classical Arabic are represented in the dialect, but there are also many new phonemes. As in other Bedouin dialects, Classical /q/ corresponds mostly to dialectal , and have merged into and the interdentals and have been preserved. In common with most Maghrebi Arabic varieties, the letter ج is realised as .
Muljačić introduced the term "Dachsprache", or "roofing language", for a dialect that serves as a standard language for other dialects. These dialects would usually be in a dialect continuum, but may be so different that mutual intelligibility is not possible between all dialects, particularly those separated by significant geographical distance. In 1982, "Rumantsch Grischun" was developed by Heinrich Schmid as such a "Dachsprache" for a number of quite different Romansh language forms spoken in parts of Switzerland. Similarly, Standard Basque and the Southern Quechua literary standard were both developed as standard languages for dialect continua that had historically been thought of as discrete languages with many dialects and no "official" dialect. Standard German and Standard Italian, to some extent, function in the same way. Perhaps the most widely used "Dachsprache" is Modern Standard Arabic, which links together the speakers of many different, often mutually unintelligible varieties of Arabic.
Kuwaiti (in Kuwaiti كويتي, //) is a Gulf Arabic dialect spoken in Kuwait. Kuwaiti Arabic shares many phonetic features unique to Gulf dialects. Due to Kuwait's soap opera industry, Kuwaiti Arabic spread throughout the Arabic-speaking world and became familiar even to people in countries such as Tunisia and Jordan.
Yemeni Americans speak both English and Arabic. They speak many different dialects of Arabic, including: Sanaani or Northern Yemeni dialect, Ta'izzi-Adeni or Southern Yemeni dialect, Hadrami dialect, Mehri dialect, and Judeo-Yemeni dialect. Most of them are Muslim.
Throughout the Arab World, Modern Standard Arabic (MSA) is the "high" standard written language and the many local colloquial dialects of Arabic are the "low" variety. However, every Arabic speaker, no matter how "cultured," is raised speaking a dialect, not the semi-artificial MSA, which must be learned formally, normally in school.
The Tihami Arabic or Tihamiyya dialect has many aspects which differentiate it from all other dialects in the Arab world. Phonologically Tihami is similar to the majority of Yemeni dialects, pronouncing the ' () as and the ' () as a velar plosive (the ' pronunciation is also shared with Egyptian Arabic) unlike San'ani and Hadhrami Arabic which pronounce the ' () as . Grammatically all Tihami dialects also share the unusual feature of replacing the definite article ("al-") with the prefix ("am-"). The future tense, much like the dialects surrounding Sanaa, is indicated with the prefix ("š-"), for all persons, e.g. "ša-būk am-sūq" "I will go to the Souq". Some Tihami dialects, such as that spoken in Al-Hodeida, are otherwise fairly similar to other Yemeni dialects in grammar and syntax, differing mainly in vocabulary, while others can be so far from any other Arabic dialect that they are practically incomprehensible even to other Yemenis.
Arab citizens of Israel, or Arab Israelis, are Israeli citizens who are Arab. Many Arab citizens of Israel self-identify as Palestinian and commonly self-designate themselves as Palestinian citizens of Israel or Israeli Palestinians, though only about 13% of them hold a Palestinian nationality ID in addition to the Israeli one. A notable percentage of Arab citizens in Israel refer to themselves as Israeli Arabs, while rejecting Palestinian identity. The traditional vernacular of most Arab citizens, irrespective of religion, is Levantine Arabic, including Lebanese Arabic in the North of Israel, Palestinian dialect of Arabic in Central Israel and Bedouin dialects across the Negev desert; having absorbed much Hebrew loanwords and phrases, the modern dialect of Arab citizens of Israel is defined by some as the "Israeli Arabic dialect". Most Arab citizens of Israel are functionally bilingual, their second language being Modern Hebrew. By religious affiliation, most are Muslim, particularly of the Sunni branch of Islam. There is a significant Arab Christian minority from various denominations as well as the Druze, among other religious communities.
On the other hand, Arabic is divided into over 27 dialects. Almost every Arab state has at least one local dialect of its own. they can be divided into 5 major branches, the Peninsula Arabic, which is the Arabic used in the Arabian peninsula, with around 9 main dialects, Arabic of the Nile Valley, which includes the Masri, Saedi, Sudanese and Chadic Arabic, the Arabic of the Fertile Crescent, which includes the Bedawi, Levant Arabic, Iraqi Arabic and North Mesopotamian Arabic, the Magharbi Arabic, which includes the Dialects used in Mauritania, Morocco, Libya, Algeria and Tunisia, also another category of Arabic is the other isolated dialects of Arabic, like the Judeo-Arabic, Mediterranean Arabic, Nubi Arabic, and the juba Arabic, which have greatly been affected by these communities' own pronunciation, culture and native tongue.
In the Sahara, more conservative Bedouin dialects, grouped under the name Saharan Arabic, are spoken; in addition, the many Sahrawi refugees at Tindouf speak Hassaniya Arabic. Most Jews of Algeria once spoke dialects of Arabic specific to their community, collectively termed Judeo-Arabic.
Tihamiyya Arabic has many aspects which differentiate it from all other dialects in the Arab world. Phonologically Tihami is similar to the majority of Yemeni dialects, pronouncing the ' () as and the ' () as a velar plosive (the "" pronunciation is also shared with Egyptian Arabic). Grammatically, all Tihami dialects also share the unusual feature of replacing the definite article ("al-") with the prefix ("am-"). The future tense, much like the dialects surrounding Sana'a, is indicated with the prefix ("š-"), for all persons, e.g. "šabūk am-sūq" "I will go to the Souq". Some Tihami dialects, such as that spoken in al Hudaydah, are otherwise fairly similar to other Yemeni dialects in grammar and syntax, differing mainly in vocabulary, while others can be so far from any other Arabic dialect that they are practically incomprehensible even to other Yemenis.
Also referred to as the sedentary Hejazi dialect, this is the form most commonly associated with the term "Hejazi Arabic", and is spoken in the urban centers of the region, such as Jeddah, Mecca, and Medina. With respect to the axis of bedouin versus sedentary dialects of the Arabic language, this dialect group exhibits features of both. Like other sedentary dialects, the urban Hejazi dialect is less conservative than the bedouin varieties in some aspects and has therefore shed some Classical forms and features that are still present in bedouin dialects, these include gender-number disagreement, and the feminine marker "-n" (see Varieties of Arabic). But in contrast to bedouin dialects, the constant use of full vowels and the absence of vowel reduction plus the distinction between the emphatic letters and is generally retained.The Arabic of today is derived principally from the old dialects of Central and North Arabia which were divided by the classical Arab grammarians into three groups: Hejaz, Najd, and the language of the tribes in adjoining areas. Though the modern Hejazi dialects has developed markedly since the development of Classical Arabic, and Modern Standard Arabic is quite distinct from the modern dialect of Hejaz. Standard Arabic now differs considerably from modern Hejazi Arabic in terms of its phonology, morphology, syntax, and lexicon, such diglossia in Arabic began to emerge at the latest in the sixth century CE when oral poets recited their poetry in a proto-Classical Arabic based on archaic dialects which differed greatly from their own.
Many Tunisian and Maghrebi words, like "qarnīṭ ("octopus")", have a Latin etymology. The dialects were later called Pre-Hilalian Arabic dialects and were used along Classical Arabic for communication in Tunisia. Also, Siculo-Arabic was spoken in several islands near Tunisia like Sicily, Pantelleria, and Malta and entered into contact with the Tunisian pre-hilalian dialects. Consequently, it ameliorated the divergence in grammar and structures of all the concerned dialects from Classical Arabic.
Many myriads of pre-Classical Arabic inscriptions are attested, in alphabets borrowed from Epigraphic South Arabian alphabets (however, Safaitic and Hismaic are not strictly Arabic, but Ancient North Arabian dialects, and written Nabataean is an Aramaic dialect):
The syntax has many similarities to other Peninsular Arabic dialects. However, the dialect contains a number of unique particles used for co-ordination, negation, and other sentence types. Examples in coordination include "but, nevertheless, though," (Classical Arabic ) "as for…," and "or."
Moroccan Arabic has many regional dialects and accents as well. Its mainstream dialect is the one used in Casablanca, Rabat and Fas and therefore it dominates the media eclipsing the other regional dialects like the ones spoken in Tangiers and Oujda. 
An important factor in the mixing or changing of Arabic is the concept of a prestige dialect. This refers to the level of respect accorded to a language or dialect within a speech community. The formal Arabic language carries a considerable prestige in most Arabic-speaking communities, depending on the context. This is not the only source of prestige, though.[3] Many studies have shown that for most speakers, there is a prestige variety of vernacular Arabic. In Egypt, for non-Cairenes, the prestige dialect is Cairo Arabic. For Jordanian women from Bedouin or rural background, it may be the urban dialects of the big cities, especially including the capital Amman.[4] Moreover, in certain contexts, a dialect relatively different from formal Arabic may carry more prestige than a dialect closer to the formal language—this is the case in Bahrain, for example.[5]
The sociolinguistic situation of Arabic in modern times provides a prime example of the linguistic phenomenon of diglossia, which is the normal use of two separate varieties of the same language, usually in different social situations. In the case of Arabic, educated Arabs of any nationality can be assumed to speak both their school-taught Standard Arabic as well as their native, mutually unintelligible "dialects"; these dialects linguistically constitute separate languages which may have dialects of their own. When educated Arabs of different dialects engage in conversation (for example, a Moroccan speaking with a Lebanese), many speakers code-switch back and forth between the dialectal and standard varieties of the language, sometimes even within the same sentence. Arabic speakers often improve their familiarity with other dialects via music or film.
The Arabic spoken by Jewish communities in the Arab world differed slightly from the Arabic of their non-Jewish neighbours. These differences were partly due to the incorporation of some words from Hebrew and other languages and partly geographical, in a way that may reflect a history of migration. For example, the Judeo-Arabic of Egypt, including in the Cairo community, resembled the dialect of Alexandria rather than that of Cairo (Blau). Similarly, Baghdad Jewish Arabic is reminiscent of the dialect of Mosul. Many Jews in Arab countries were bilingual in Judeo-Arabic and the local dialect of the Muslim majority.
