'''Azerbaijani''' ({{IPAc-en|ˌ|æ|z|ər|b|aɪ|ˈ|dʒ|æ|n|i|,_|-|ɑː|n|i}} {{respelling|AZ|ər|by|JAN|ee}}) or '''Azeri''' ({{IPAc-en|æ|ˈ|z|ɛər|i|,_|ɑː|-|,_|ə|-}} {{respelling|az|AIR|ee|,_|ah-|,_|ə-}}), also referred to as '''Azeri Turkic''' or '''Azeri Turkish''', is a [[Turkic languages|Turkic language]] from the [[Oghuz languages|Oghuz]] sub-branch.  It is spoken primarily by the [[Azerbaijanis|Azerbaijani people]], who live mainly in the [[Azerbaijan|Republic of Azerbaijan]], where the North Azerbaijani [[Variety (linguistics)|variety]] is spoken, while [[Iranian Azerbaijanis]] in the [[Azerbaijan (Iran)|Azerbaijan]] region of [[Iran]], speak the South Azerbaijani [[Variety (linguistics)|variety]]. Azerbaijani has [[Official language|official]] status in the Republic of Azerbaijan and [[Dagestan]] (a [[Federal subjects of Russia|federal subject of Russia]]), but it does not have official status in Iran, where the majority of [[Iranian Azerbaijanis|Iranian Azerbaijani]] people live. Azerbaijani is also spoken to lesser varying degrees in Azerbaijani communities of [[Georgia (country)|Georgia]] and [[Turkey]] and by [[Azerbaijani diaspora|diaspora]] communities, primarily in Europe and North America.

Although there is a high degree of [[mutual intelligibility]] between both forms of Azerbaijani, there are significant differences in [[phonology]], [[lexicon]], [[morphology (linguistics)|morphology]], [[syntax]], and sources of [[loanword]]s. The [[standard language|standardized form]] of North Azerbaijani (spoken in the Republic of Azerbaijan and Russia) is based on the [[Shirvan]]i dialect, while South Azerbaijani uses variety of regional dialects. Since the Republic of Azerbaijan's independence from the [[Soviet Union]] in 1991, Northern Azerbaijani has used the Latin script. On the other hand, South Azerbaijani has always used and continues to use the [[Perso-Arabic script]]. 

Azerbaijani is closely related to [[Turkmen language|Turkmen]], [[Turkish language|Turkish]], [[Gagauz language|Gagauz]], and [[Qashqai language|Qashqai]], being mutually intelligible with each of these languages to varying degrees.

== Etymology and background ==
Historically, the language was referred to by its native speakers as {{lang|az|türk dili}} or {{lang|az|türkcə}},<ref>{{cite web|url= http://www.bbc.com/azeri/analysis/2016/08/160809_azer_turk_language | title= Türk dili, yoxsa azərbaycan dili? (Turkish language or Azerbaijani language?) |website= [[BBC]] |date= 9 August 2016 |access-date= 15 August 2016|language=az}}</ref> meaning either "Turkish" or "Turkic". In the early years following the establishment of the [[Azerbaijan Soviet Socialist Republic]], the language was still referred to as "Turkish" in official documents. However, in the 1930s, its name was officially changed to "Azerbaijani".<ref>{{Cite web |last=Goyushov |first=Altay |date=26 September 2018 |title=The Language of Azerbaijan: Turkish or Azerbaijani? |url=https://bakuresearchinstitute.org/en/azerbaijani-turk-dili-yoxsa-az%C9%99rbaycan-dili/ |access-date=23 August 2023 |website=Baku Research Institute |quote=However, in 1936–1937, the situation changed fundamentally. Even though there was no explicit mention of an enactment of state language in local Azerbaijani laws, the term “Turkish” was substituted by “Azerbaijani” in state and court documents. Later in 1956, “Azerbaijani” was given the status of the official state language of Soviet Azerbaijan. This was also mentioned in Soviet Azerbaijan's last Constitution adopted in 1978.}}</ref><ref name="iranicaonline.org">{{Encyclopædia Iranica Online|url=https://iranicaonline.org/articles/azerbaijan-viii|title=AZERBAIJAN|year=1987|access-date=14 February 2023}}</ref> The language is often still referred to as ''Turki'' or ''Torki'' in [[Iranian Azerbaijan]].<ref>{{Cite book |last=Rahmati |first=Nemat |url=https://www.worldcat.org/oclc/40415729 |title=Aserbaidschanisch Lehrbuch : unter Berücksichtigung des Nord- und Südaserbaidschanischen |date=1998 |publisher=Harrassowitz |others=Korkut M. Buğday |isbn=978-3-447-03840-9 |location=Wiesbaden |oclc=40415729}}</ref> The term "Azeri", generally interchangeable with "Azerbaijani", is from Turkish ''Azeri''<ref>{{Cite book |last=Stevenson |first=Angus |title=Oxford dictionary of English |publisher=Oxford University Press |year=2010 |isbn=9780199571123 |pages=113}}</ref> which is used for the people (''azerice'' being used for the language in Turkish), itself from Persian آذری, Āzarī. The term is also used for [[Old Azeri]], the ancient Iranian language spoken in the region until the 17th century.

== History and evolution ==
{{Main|Languages of Azerbaijan|Languages of Iran}}
Azerbaijani evolved from the Eastern branch of [[Oghuz languages|Oghuz Turkic]] ("Western Turkic")<ref>"The Turkic Languages", Osman Fikri Sertkaya (2005) in ''Turks – A Journey of a Thousand Years, 600–1600'', London {{ISBN|978-1-90397-356-1}}</ref> which spread to the Caucasus, in [[Eastern Europe]],<ref>{{cite book|last1=Wright|first1=Sue|last2=Kelly|first2=Helen|title=Ethnicity in Eastern Europe: Questions of Migration, Language Rights and Education|date=1998|publisher=Multilingual Matters Ltd.|isbn=978-1-85359-243-0|page=49}}</ref><ref>{{cite book|last1=Bratt Paulston|first1=Christina|last2=Peckham|first2=Donald|title=Linguistic Minorities in Central and Eastern Europe|date=1 October 1998|publisher=Multilingual Matters Ltd.|isbn=978-1-85359-416-8|pages=98–115}}</ref> and northern Iran, in [[Western Asia]], during the medieval [[Turkic migration]]s.<ref name="elements">{{Encyclopædia Iranica Online|url=https://iranicaonline.org/articles/azerbaijan-ix|title=AZERBAIJAN ix. Iranian Elements in Azeri Turkish|first=Lars|last=Johanson|year=1988|access-date=14 February 2023}}</ref> [[Persian language|Persian]] and [[Arabic]] influenced the language, but Arabic words were mainly transmitted through the intermediary of literary Persian.<ref>John R. Perry, "Lexical Areas and Semantic Fields of Arabic" in Csató ''et al.'' (2005) ''Linguistic convergence and areal diffusion: case studies from Iranian, Semitic and Turkic'', Routledge, p. 97: "It is generally understood that the bulk of the Arabic vocabulary in the central, contiguous Iranic, Turkic and Indic languages was originally borrowed into literary Persian between the ninth and thirteenth centuries CE..."</ref> Azerbaijani is, perhaps after [[Uzbek language|Uzbek]], the Turkic language upon which Persian and other [[Iranian languages]] have exerted the strongest impact—mainly in phonology, syntax, and vocabulary, less in morphology.<ref name="elements" />

The Turkic language of Azerbaijan gradually supplanted the Iranian languages in what is now northwestern Iran, and a variety of [[languages of the Caucasus]] and [[Iranian languages]] spoken in the [[Caucasus]], particularly [[Udi language|Udi]] and [[Old Azeri language|Old Azeri]]. By the beginning of the 16th century, it had become the dominant language of the region. It was one of the spoken languages in the court of the [[Safavid Iran|Safavids]], [[Afsharid dynasty|Afsharids]] and [[Qajar Iran|Qajars]].

The historical development of Azerbaijani can be divided into two major periods: early ({{circa|14th}} to 18th century) and modern (18th century to present). Early Azerbaijani differs from its descendant in that it contained a much larger number of Persian and Arabic loanwords, phrases and syntactic elements. Early writings in Azerbaijani also demonstrate linguistic interchangeability between Oghuz and Kypchak elements in many aspects (such as pronouns, case endings, participles, etc.). As Azerbaijani gradually moved from being merely a language of [[epic poetry|epic]] and [[lyric poetry]] to being also a language of [[journalism]] and [[science|scientific]] [[research]], its literary version has become more or less unified and simplified with the loss of many archaic Turkic elements, stilted Iranisms and Ottomanisms, and other words, expressions, and rules that failed to gain popularity among the Azerbaijani masses.

The [[Russian Empire|Russian]] annexation of [[Qajar Iran|Iran]]'s territories in the [[Caucasus]] through the [[Russo-Persian Wars|Russo-Iranian wars]] of [[Russo-Persian War (1804–1813)|1804–1813]] and [[Russo-Persian War (1826–1828)|1826–1828]] split the language community across two states. Afterwards, the Tsarist administration encouraged the spread of Azerbaijani in eastern Transcaucasia as a replacement for Persian spoken by the upper classes, and as a measure against Persian influence in the region.<ref>{{cite journal |last1=Tonoyan |first1=Artyom |title=On the Caucasian Persian (Tat) Lexical Substratum in the Baku Dialect of Azerbaijani. Preliminary Notes |journal=Zeitschrift der Deutschen Morgenländischen Gesellschaft |date=2019 |volume=169 |issue=2 |page=368 (note 4) |doi=10.13173/zeitdeutmorggese.169.2.0367|s2cid=211660063 }}</ref><ref>{{cite book |last1=Karpat |first1=K. |title=The Politicization of Islam: Reconstructing Identity, State, Faith, and Community in the Late Ottoman State |date=2001 |publisher=Oxford University Press |page=295}}</ref>

Between {{circa|1900}} and 1930, there were several competing approaches to the unification of the national language in what is now the Azerbaijan Republic, popularized by scholars such as [[Hasan bey Zardabi]] and [[Mammad agha Shahtakhtinski]]. Despite major differences, they all aimed primarily at making it easy for semi-literate masses to read and understand literature. They all criticized the overuse of Persian, Arabic, and European elements in both colloquial and literary language and called for a simpler and more popular style.

The [[Soviet Union]] promoted the development of the language but set it back considerably with two successive script changes<ref>{{cite web|url= http://www.azer.com/aiweb/categories/magazine/81_folder/81_articles/81_alphabet_changes1.html|title=Alphabet Changes in Azerbaijan in the 20th Century|website=[[Azerbaijan International]]|date=Spring 2000|access-date=21 July 2013}}</ref> – from the [[Persian alphabet|Persian]] to [[Latin alphabet|Latin]] and then to the [[Cyrillic script]] – while [[Iranian Azerbaijanis]] continued to use the Persian script as they always had. Despite the wide use of Azerbaijani in the [[Azerbaijan Soviet Socialist Republic]], it became the official language of Azerbaijan only in 1956.<ref>[http://news.day.az/politics/249744.html Language Commission Suggested to Be Established in National Assembly]. ''Day.az''. 25 January 2011.</ref> After independence, the Republic of Azerbaijan decided to switch back to a modified Latin script.

In the mid-19th century, Azerbaijani literature was taught at schools in [[Baku]], [[Ganja, Azerbaijan|Ganja]], [[Shaki, Azerbaijan|Shaki]], [[Tbilisi]], and [[Yerevan]]. Since 1845, it has also been taught in the [[Saint Petersburg State University]] in [[Russia]]. In 2018, Azerbaijani language and literature programs are offered in the United States at several universities, including [[Indiana University]], [[UCLA]], and [[University of Texas at Austin]].<ref name="auto"/> The vast majority, if not all Azerbaijani language courses teach North Azerbaijani written in the Latin script and not South Azerbaijani written in the Perso-Arabic script.

Modern literature in the Republic of Azerbaijan is primarily based on the [[Shirvan]]i dialect, while in the [[Azerbaijan (Iran)|Iranian Azerbaijan]] region (historic Azerbaijan) it is based on the [[Tabriz]]i one.

Beginning in 1834, it was introduced as a language of study in [[Kutaisi]] instead of Armenian.

Azerbaijani is one of the [[Oghuz languages]] within the [[Turkic languages|Turkic language family]]. ''[[Ethnologue]]'' lists North Azerbaijani (spoken mainly in the Republic of Azerbaijan and Russia) and South Azerbaijani (spoken in Iran, Iraq, and Syria) as two groups within the Azerbaijani [[macrolanguage]] with "significant differences in phonology, lexicon, morphology, syntax, and loanwords" between the two.<ref name="Ethnologue 22 AZJ"/> The [[International Organization for Standardization]] (ISO) considers Northern and Southern Azerbaijani to be distinct languages.<ref name="Cogent Education">{{cite journal |last1=Salehi |first1=Mohammad |last2=Neysani |first2=Aydin |title=Receptive intelligibility of Turkish to Iranian-Azerbaijani speakers |journal=Cogent Education |date=2017 |volume=4 |issue=1 |page=3 |doi=10.1080/2331186X.2017.1326653 |s2cid=121180361 |quote=Northern and Southern Azerbaijani are considered distinct languages by the International Organization for Standardization (ISO) (...)|doi-access=free }}</ref> [[Linguist]]s Mohammad Salehi and Aydin Neysani write that "there is a high degree of mutual intelligibility" between North and South Azerbaijani.<ref name="Cogent Education" />

Three varieties have been accorded [[ISO 639-3]] language codes: North Azerbaijani, South Azerbaijani and [[Qashqai language|Qashqai]]. The ''[[Glottolog]]'' 4.1 database classifies North Azerbaijani, with 20 dialects, and South Azerbaijani, with 13 dialects, under the Modern Azeric family, a branch of Central Oghuz.<ref name="Glottolog">{{cite book|editor-last1=Hammarström |editor-first1=Harald |editor-last2=Forkel |editor-first2=Robert |editor-last3=Haspelmath |editor-first3=Martin |access-date=5 February 2020|title=Modern Azeric|chapter-url=https://glottolog.org/resource/languoid/id/mode1262|date=2019 |doi=10.5281/zenodo.3554959 |via=[[Glottolog 4.1]]|last1=Hammarström |first1=Harald |last2=Forkel |first2=Robert |last3=Haspelmath |first3=Martin |chapter=Linguistics }}</ref>

=== North Azerbaijani ===
[[File:E60 Älät.jpg|thumb|Azerbaijani-language road sign.]]

North Azerbaijani,<ref name="Ethnologue 22 AZJ"/> or Northern Azerbaijani, is the [[official language]] of the [[Republic of Azerbaijan]]. It is closely related to modern-day Istanbul Turkish, the official language of Turkey. It is also spoken in southern [[Dagestan]], along the [[Caspian Sea|Caspian coast]] in the southern [[Caucasus Mountains]] and in scattered regions throughout [[Central Asia]]. {{as of|2011}}, there are some 9.23 million speakers of North Azerbaijani including 4 million [[monolingual]] speakers (many North Azerbaijani speakers also speak Russian, as is common throughout former USSR countries).<ref name="Ethnologue 22 AZJ"/>

The Shirvan dialect as spoken in [[Baku]] is the basis of standard Azerbaijani. Since 1992, it has been officially written with a Latin script in the Republic of Azerbaijan, but the older Cyrillic script was still widely used in the late 1990s.{{sfn|Schönig|1998|p=248}}

''Ethnologue'' lists 21 North Azerbaijani dialects: "Quba, Derbend, Baku, Shamakhi, Salyan, Lenkaran, Qazakh, Airym, Borcala, [[Terekeme people|Terekeme]], [[Qizilbash|Qyzylbash]], Nukha, Zaqatala (Mugaly), Qabala, Nakhchivan, Ordubad, Ganja, Shusha (Karabakh), [[Karapapakhs|Karapapak]], Kutkashen, Kuba".<ref name="Ethnologue 22 AZJ"/>

In [[Iran]], the [[Persian language|Persian]] word for Azerbaijani is borrowed as ''{{lang|az|Torki}}'' "Turkic".<ref name="Ethnologue 22 AZB"/> In Iran, it is spoken mainly in [[East Azerbaijan Province|East Azerbaijan]], [[West Azerbaijan Province|West Azerbaijan]], [[Ardabil Province|Ardabil]] and [[Zanjan Province|Zanjan]].

Linguistically, Afshārī is classified as a dialect belonging to the South Oghuz group of Turkic languages (southwestern branch of Turkic) (Johanson, History of Turkic, 82–3), or else as a dialect of South Azerbaijani (Azeri). As they were embedded in a Fārsī-speaking environment, however, in many cases Fārsī became the mother tongue of the Afshārs. Other groups became bilingual (as in Kirmān). Additionally, the contact between the different languages seems to have transformed the original dialect (cf. Johanson, Discoveries, 14–6).

Несмотря на все уверения, что азербайджанский является ближайшим родственником турецкого, это не так. Наиболее близким к нему (азербайджанскому) является туркменский. Распад этого единства попадает примерно на 1180-й год. Это удивительно. Потому что тогда как раз был конец Империи Великих Сельджуков. <...> Интересная дата – это распад огузской общности и выделение турецкого языка. Это примерно 1030-й год. Это самое начало 11-го века. Это очень интересно, потому что как раз в это время начинается миграция сельджуков. <...> Собственно сердце турецкого языка – это район Рума в Восточной Анатолии, где сидит тюркское население.}}</ref>

=== Azerbaijani and Turkish ===
[[File:Oghuz Turkic Languages distribution map.png|thumb|[[Turkish language|Turkish]], Azerbaijani, and [[Turkmen language|Turkmen]] are [[Oghuz languages]]]]
Speakers of Turkish and Azerbaijani can, to an extent, communicate with each other as both languages have substantial variation and are to a degree mutually intelligible, though it is easier for a speaker of Azerbaijani to understand Turkish than the other way around.<ref>{{Cite web |title=Azerbaijani (Azeri) |url=https://en.unesco.org/silkroad/silk-road-themes/languages-and-endanger-languages/azerbaijani-azeri |publisher=UNESCO}}</ref> [[Turkish television drama#Turkic countries|Turkish soap operas]] are very popular with Azeris in both Iran and Azerbaijan. [[Reza Shah Pahlavi]] of [[Iran]] (who spoke South Azerbaijani) met with [[Mustafa Kemal Atatürk]] of [[Turkey]] (who spoke Turkish) in 1934; the two were filmed speaking their respective language to each other and communicated effectively.<ref name="Yelda2012">{{Cite book |last=Yelda |first=Rami |url=https://books.google.com/books?id=_Kbj21wrwwEC&pg=PT33 |title=A Persian Odyssey: Iran Revisited |publisher=AuthorHouse |year=2012 |isbn=978-1-4772-0291-3 |page=33}}</ref><ref name="MafinezamMehrabi2008">{{Cite book |last=Mafinezam |first=Alidad |url=https://books.google.com/books?id=PO_s9H5QTp4C&pg=PA57 |title=Iran and Its Place Among Nations |last2=Mehrabi |first2=Aria |publisher=Greenwood Publishing Group |year=2008 |isbn=978-0-275-99926-1 |page=57}}</ref>

In a 2011 study, 30 Turkish participants were tested to determine how well they understood written and spoken Azerbaijani. It was found that even though Turkish and Azerbaijani are typologically similar languages, on the part of Turkish speakers the intelligibility is not as high as is estimated.<ref>{{Cite journal |last=Sağın-Şimşek |first=Çiğdem |last2=König |first2=Wolf |date=September 2012 |title=Receptive multilingualism and language understanding: Intelligibility of Azerbaijani to Turkish speakers |url=http://journals.sagepub.com/doi/10.1177/1367006911426449 |journal=International Journal of Bilingualism |language=en |volume=16 |issue=3 |pages=315–331 |doi=10.1177/1367006911426449 |issn=1367-0069}}</ref> In a 2017 study, [[Iranian Azerbaijanis]] scored in average 56% of receptive intelligibility in spoken language of Turkish.<ref>{{Cite journal |last=Salehi |first=Mohammad |last2=Neysani |first2=Aydin |date=2017 |title=Receptive intelligibility of Turkish to Iranian-Azerbaijani speakers |journal=Cogent Education |volume=4 |issue=1 |page=10 |doi=10.1080/2331186X.2017.1326653 |s2cid=121180361 |doi-access=free}}</ref>

Azerbaijani exhibits a similar stress pattern to Turkish but simpler in some respects.

=== Azerbaijani and Turkmen ===
The 1st person personal pronoun is ''mən'' in Azerbaijani just as ''men'' in [[Turkmen language|Turkmen]], whereas it is ''ben'' in Turkish. The same is true for demonstrative pronouns ''bu'', where sound ''b'' is replaced with sound ''m''. For example: ''bunun''>''munun''/''mının'', ''muna''/''mına'', ''munu''/''munı'', ''munda''/''mında'', ''mundan''/''mından''.<ref>Shiraliyev M. Fundamentals of Azerbaijan dialectology. Baku, 2008. p.76</ref> This is observed in the Turkmen literary language as well, where the [[demonstrative pronoun]] ''bu'' undergoes some changes just as in: ''munuñ'', ''munı'', ''muña'', ''munda'', ''mundan'', ''munça''.<ref>Kara M. Turkmen Grammar. Ankara, 2005. p.231</ref> ''b''>''m'' replacement is encountered in many dialects of the Turkmen language and may be observed in such words as: ''boyun''>''moyın'' in [[Yomut]] – Gunbatar dialect, ''büdüremek''>''müdüremek'' in [[Ersari]] and Stavropol Turkmens' dialects, ''bol''>''mol'' in [[Karakalpaks|Karakalpak]] Turkmens' dialects, ''buzav''>''mizov'' in Kirac dialects.<ref>{{cite book|author1=Berdiev R.|author2=S.

== Phonology ==
=== Phonotactics ===
Azerbaijani [[phonotactics]] is similar to that of other Oghuz Turkic languages, except:
* [[Mora (linguistics)|Trimoraic]] syllables with long vowels are permissible.
* There is an ongoing [[Metathesis (linguistics)|metathesis]] of neighboring consonants in a word.{{sfn|Kök|2016|pp=406–30}} Speakers tend to reorder consonants in the order of decreasing sonority and back-to-front (for example, iləri becomes irəli, köprü becomes körpü, topraq becomes torpaq). Some of the metatheses are so common in the educated speech that they are reflected in orthography (all the above examples are like that). This phenomenon is more common in rural dialects but observed even in educated young urban speakers, but noticeably absent from some Southern dialects.
* Intramorpheme q {{IPA|/g/}} becomes {{IPA|/x/}}.

The typical phonetic quality of South Azerbaijani vowels is as follows:
* {{IPA|/i, u, æ/}} are close to cardinal {{IPA|[{{IPAplink|i}}, {{IPAplink|u}}, {{IPAplink|a}}]}}.{{sfnp|Mokari|Werner|2016|p=509}}
* The F1 and F2 formant frequencies overlap for {{IPA|/œ/}} and {{IPA|/ɯ/}}. Their [[formant|acoustic quality]] is more or less close-mid central {{IPA|[{{IPAplink|ɵ}}, {{IPAplink|ɘ}}]}}. The main role in the distinction of two vowels is played by the different F3 frequencies in audition,{{sfn|Mokari|Werner|2016|p=514}} and rounding in articulation. Phonologically, however, they are more distinct: {{IPA|/œ/}} is phonologically a mid front rounded vowel, the front counterpart of {{IPA|/o/}} and the rounded counterpart of {{IPA|/e/}}. {{IPA|/ɯ/}} is phonologically a close back unrounded vowel, the back counterpart of {{IPA|/i/}} and the unrounded counterpart of {{IPA|/u/}}.
* The other mid vowels {{IPA|/e, o/}} are closer to close-mid {{IPA|[{{IPAplink|e}}, {{IPAplink|o}}]}} than open-mid {{IPA|[{{IPAplink|ɛ}}, {{IPAplink|ɔ}}]}}.{{sfnp|Mokari|Werner|2016|p=509}}
* {{IPA|/ɑ/}} is phonetically near-open back {{IPAblink|ɑ|ɑ̝}}.{{sfnp|Mokari|Werner|2016|p=509}}

==== Diphthongs ====
The modern Azerbaijani Latin alphabet contains the digraphs {{Lang-az|ov|label=none}} and ''{{Lang-az|öv|label=none}}'' to represent diphthongs present in the language, and the pronunciation of diphthongs is today accepted as the norm in the orthophony of Azerbaijani.{{sfn|Əlizadə|2020|pp=10–12}} Despite this, the number and even the existence of diphthongs in Azerbaijani has been disputed, with some linguists, such as {{interlanguage link|Abdulazal Damirchizade|az|Əbdüləzəl Dəmirçizadə}}, arguing that they are non-phonemic. Damirchizade's view was challenged by others, such as {{interlanguage link|Aghamusa Akhundov|az|Ağamusa Axundov}}, who argued that Damirchizade was taking orthography as the basis of his judgement, rather than its phonetic value. According to Akhundov, Azerbaijani contains two diphthongs, {{IPAslink|ou̯}} and {{IPAslink|œy̯}},{{refn|They are /oʋ/ and /œw/ in the dialect of Tabriz.{{sfn|Səlimi|1976|pp=49–51}}}} represented by {{Lang-az|ov|label=none}} and ''{{Lang-az|öv|label=none}}'' in the alphabet, both of which are phonemic due to their contrast with {{IPAslink|o}} and {{IPAslink|œ}}, represented by {{Lang-az|o|label=none}} and ''{{Lang-az|ö|label=none}}''.{{sfn|Səlimi|1976|pp=33–34, 44–51}} In some cases, a non-syllabic {{IPAslink|v}} can also be pronounced after the aforementioned diphthongs, to form {{IPAslink|ou̯v}} and {{IPAslink|œy̯v}}, the rules of which are as follows:{{Sfn|Əlizadə|2020|p=12}}

* If the letter {{Lang-az|o|label=none}} precedes {{Lang-az|v|label=none}} and then {{Lang-az|u|label=none}}, forming {{Lang-az|ovu|label=none}}, it should be pronounced as {{IPAslink|ou̯}}, e.g. [[wiktionary:sovurmaq#Azerbaijani|sovurmaq]], {{IPA-az|sou̯rˈmɑx|pron}}.
* If the letter {{Lang-az|o|label=none}} precedes {{Lang-az|v|label=none}} and then any consonant, it should be pronounced as {{IPAslink|ou̯(<span class="ltr">v</span>)}}, with the pronunciation of the {{Lang-az|v|label=none}} being optional, e.g. [[wiktionary:dovşan#Azerbaijani|dovşan]], {{IPA-az|dou̯(<span class="ltr">v</span>)ˈʃɑn|pron}}.
* If the letter {{Lang-az|ö|label=none}} precedes {{Lang-az|v|label=none}} and then any [[unvoiced consonant]], it should be pronounced as {{IPAslink|œy̯}}, e.g. [[wiktionary:cövhər#Azerbaijani|cövhər]], {{IPA-az|d͡ʒœy̯ˈhær|pron}}.
* If the letter {{Lang-az|ö|label=none}} precedes {{Lang-az|v|label=none}} and then any [[voiced consonant]], it should be pronounced as {{IPAslink|œy̯(<span class="ltr">v</span>)}}, with the pronunciation of the {{Lang-az|v|label=none}} being optional, e.g. [[wiktionary:tövbə#Azerbaijani|tövbə]], {{IPA-az|tœy̯(<span class="ltr">v</span>)ˈbæ|pron}}.

Modern linguists who have examined Azerbaijani's vowel system almost unanimously have recognised that diphthongs are phonetically produced in speech.{{sfn|Səlimi|1976|pp=89}}

== Writing systems ==
{{Main|Azerbaijani alphabet}}
Before 1929, Azerbaijani was written only in the [[Perso-Arabic alphabet]], an [[Abjad#Impure abjads|impure abjad]] that does not represent all vowels (without [[diacritical marks]]). In Iran, the process of standardization of orthography started with the publication of Azerbaijani magazines and newspapers such as ''[[Varlyq|Varlıq]]'' ({{lang|az-Arab|وارلیق}} — ''Existence'') from 1979. Azerbaijani-speaking scholars and literarians showed great interest in involvement in such ventures and in working towards the development of a standard writing system. These effort culminated in language seminars being held in [[Tehran]], chaired by the founder of ''Varlıq'', [[Javad Heyat]], in 2001 where a document outlining the standard orthography and writing conventions were published for the public.<ref name=":0">Azeri Arabic Turk standard of writing; authored by Javad Heyat; 2001 http://www.azeri.org/Azeri/az_arabic/azturk_standard.pdf</ref> This standard of writing is today canonized by a Persian–Azeri Turkish dictionary in Iran titled {{lang|fa-Latn|Loghatnāme-ye Torki-ye Āzarbāyjāni}}.<ref>{{Cite book |last=Ameli |first=Seyed Hassan |title=لغت‌نامه ترکی آذربایجانی: حروف آ (جلد ۱ |publisher=Mohaghegh Ardabili |year=2021 |isbn=978-600-344-624-3 |language=fa, az }}</ref>

In 1929–1938 a Latin alphabet was in use for North Azerbaijani (although it was different from the one used now), from 1938 to 1991 the [[Cyrillic script]] was used, and in 1991 the current Latin alphabet was introduced, although the transition to it has been rather slow.<ref>{{cite web |last1=Dooley |first1=Ian |title=New Nation, New Alphabet: Azerbaijani Children's Books in the 1990s |url=https://blogs.princeton.edu/cotsen/2017/10/new-nation-new-alphabet-azerbaijani-childrens-books-in-the-1990s/ |website=Cotsen Children's Library |publisher=Princeton University WordPress Service |access-date=13 December 2017 |language=en, az |date=6 October 2017 |quote=Through the 1990s and early 2000s Cyrillic script was still in use for newspapers, shops, and restaurants.

The Azerbaijani Latin alphabet is based on the Turkish Latin alphabet, which in turn was based on former Azerbaijani Latin alphabet because of their linguistic connections and mutual intelligibility. The letters {{lang|az|Әə}}, {{lang|az|Xx}}, and {{lang|az|Qq}} are available only in Azerbaijani for sounds which do not exist as separate phonemes in Turkish.

Northern Azerbaijani, unlike Turkish, respells foreign names to conform with Latin Azerbaijani spelling, e.g. [[wikt:Bush|Bush]] is spelled {{lang|az|Buş}} and [[Schröder]] becomes {{lang|az|Şröder}}. Hyphenation across lines directly corresponds to spoken syllables, except for geminated consonants which are hyphenated as two separate consonants as morphonology considers them two separate consonants back to back but enunciated in the onset of the latter syllable as a single long consonant, as in other [[Turkic languages]].{{citation needed|date=November 2020}}

** ''{{lang|az|Aman}}'' ("Mercy")
** ''{{lang|az|Çox şükür}}'' ("Much thanks")
* explicitly:
** ''{{lang|az|Allah Allah}}'' (pronounced as ''{{lang|az|Allahallah}}'') ("Goodness gracious")
** ''{{lang|az|Hay Allah}}''; ''{{lang|az|Vallah}}'' "By God [I swear it]".
** ''{{lang|az|Çox şükür allahım}}'' ("Much thanks my God")

=== Formal and informal ===
{{Unreferenced section|date=October 2020}}
Azerbaijani has informal and formal ways of saying things. This is because there is a strong [[T-V distinction|tu-vous distinction]] in Turkic languages like Azerbaijani and Turkish (as well as in many other languages). The informal "you" is used when talking to close friends, relatives, animals or children. The formal "you" is used when talking to someone who is older than the speaker or to show respect (to a professor, for example).

As in many Turkic languages, personal pronouns can be omitted, and they are only added for emphasis. 

Since 1992 North Azerbaijani has used a phonetic writing system, so pronunciation is easy: most words are pronounced exactly as they are spelled. However, the combination {{Lang-az|qq|label=none}} in words is pronounced {{IPA-az|kɡ|}}, as the first [[voiced velar stop]] is [[devoiced]] when it is [[geminated]], such as in [[wiktionary:çaqqal#Azerbaijani|çaqqal]], {{IPA-az|t͡ʃɑkɡɑl|pron}}.{{Sfn|Əlizadə|2020|p=14}}{{Sfn|Səlimi|1976|p=38–39}}
