Hijazi Arabic (Arabic: حجازي) (also known as Hejazi Arabic [ISO 639-3], West Arabian Arabic) is a variety of the Arabic language spoken in the western region of Saudi Arabia. Although, strictly speaking, there are two distinct dialects spoken in the Hejaz region, one by the bedouin and rural tribes, and another by the urban population, the term most often applies to the urban variety, spoken in cities such as Jeddah, Mecca, Yanbu, and Medina. Outside of Arabia, Urban Hejazi appears to be most closely related to the Arabic dialects of Northern Sudan and Upper Egypt (Ingham 1971).
Urban Hijazi Dialect 
Also referred to as the sedentary Hijazi dialect, this is the form most commonly associated with the term "Hijazi 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.
Bedouin Features 
The most prominent of these are the following:
- The qaaf (ق) of Standard Arabic is voiced and pronounced /ɡ/ (as in the English word "get").
- Hejazi Arabic does not employ double negation, nor does it append the negation particles -sh to negate verbs (Hejazi Ma A'rif, as opposed to Egyptian Ma'rafsh and Palestinian Bi'rafish, meaning "I don't know")
- The prohibitive mood of Classical Arabic is preserved in the imperative (la taruuh "don't go").
- The possessive suffixes are generally preserved in their Classical forms. For example, beitakum ("your house") plural form.
Sedentary Features 
Like other sedentary dialects, the urban Hejazi dialect is less conservative than the bedouin varieties and has therefore shed many Classical forms and features that are still present in many bedouin dialects. These include the internal passive form (which in Hejazi, is replaced by the pattern anfa'al"/"yinfa'il), the marker for indefiniteness (tanwin), gender-number disagreement, and the feminine marker -n (see Varieties of Arabic). Features that mark Hejazi Arabic as a sedentary dialect include:
- The present progressive tense is marked by /ɡaʕid/, /ʕammal/ or the prefix bi- (gaʕid/ʕammal yiktub or biyidrus, "he is studying").
- The interdental /θ/ ث (as in English "three") is mostly rendered "t", while the interdental /ð/ ذ (as in English "this") is mostly rendered "d" and sometimes "z" like in the word ("kazaba"). They remain interdental in the countryside.
- In contrast to bedouin dialects, the distinction between the emphatic sounds /dˤ/ ض and /ðˤ/ ظ is generally preserved.
- The final -n in present tense plural verb forms is no longer employed (e.g. yirkabu instead of yirkabun)
- The dominant case ending before the 3rd person masculine singular pronoun is -u, rather than the -a that is prevalent in bedouin dialects. For example, beituh ("his house"), 'induh ("with him"), 'arafuh ("he knew him").
- Possessive pronouns for the 2nd person are -ak (masculine) and -ik (feminine). In Standard Arabic, these are -ka and -ki, respectively, while in bedouin dialects they are -ik and -its or some variation thereof...
Other Features 
Other features of Hejazi Arabic are:
- Compared to neighboring dialects, urban Hejazi retains more of the short vowels of Standard Arabic, for example:
- samaka ("fish"), as opposed to bedouin smika, and Syrian samake
- darabatu ضربَته ("she hit him"), as opposed to bedouin dribtah
- uktub ("write", Imperative mood), as opposed to bedouin iktib, and Syrian ktoub
- 'indakum عندَكُم ("in your [plural] possession"), as opposed to bedouin 'indikom, Egyptian 'andoko, and Lebanese 'andkun
- The plural first person pronoun is nihna (نحنا) or ihna (إحنا), as opposed to the the bedouin hinna (حنّا) and inna (إنّا).
- When used to indicate location, the preposition fee في is preferred to b بـ (fee Makkah, meaning "in Mecca"). In bedouin dialects, the preference differs by region.
- Less restriction on the distribution of /i/ and /u/.
- /a/ is more retracted: [ä].
- The glottal stop can be added to final syllables ending in a vowel as a way of emphasising.
- The first person suffix pronoun is -ni.
The urban Hejazi vocabulary differs in some respect from that of other dialects in the Arabian Peninsula. For example, there are fewer specialized terms related to desert life, and more terms related to seafaring and fishing. Due to the diverse origins of the inhabitants of Hijazi cities, many borrowings from the dialects of Egypt, Syria, and Yemen exist. Five centuries of Turkish rule have also had their influence. Due to this, the Hijazi dialect is considered to be of "mixed affinities" (Ingham 1971).
Certain distinctive particles and vocabulary in Hijazi are /ɡiːd/ "already", /daħħin/ "now", and /lessa/ "not yet".
Bedouin Hejazi Dialects 
The varieties of Arabic spoken by the bedouin tribes of the Hejaz region are relatively under-studied. However, the speech of some tribes shows much closer affinity to other bedouin dialects, particularly those of neighboring Nejd, than to those of the Hejazi cities. The dialects of northern Hejazi tribes merge into those of Jordan and Sinai, while the dialects in the south merge with those of 'Asir and Nejd. It is also worth noting that many large tribal confederations in Nejd and eastern Arabia are recent migrants from the Hejaz, including the tribes of Utaybah, Mutayr, Harb, and Bani Khalid. In earlier times, many other Arab tribes also came from the Hejaz, including Kinanah, Juhayna, Banu Sulaym, and Ghatafan. Also, not all speakers of these bedouin dialects are literally nomadic bedouins; some are simply sedentary sections that live in rural areas, and thus speak dialects similar to those of their bedouin neighbors.
