Kurdish phonology

Kurdish phonology is the sound system of the Kurdish dialect continuum. This article includes the phonology of the three Kurdish dialects in their standard form respectively. Phonological features include the distinction between aspirated and unaspirated voiceless stops and the presence of facultative phonemes.[1][2]


Geographic distribution of Kurdish and Zaza–Gorani [3]

  • /n, t, d/ are laminal denti-alveolar [, , ], while /s, z/ are dentalized laminal alveolar [, ],[6] pronounced with the blade of the tongue very close to the back of the upper front teeth, with the tip resting behind lower front teeth.
  • Kurdish contrasts plain alveolar /l/ and velarized postalveolar[7] /ɫ/ lateral approximants. Unlike in English, the sounds are separate phonemes rather than allophones.[8]
  • Postvocalic /d/ is lenited to an approximant [ð̞]. This is a regional feature occurring in other Iranian languages as well and called by Windfuhr the "Zagros d".[9]
  • Kurdish has two rhotic sounds; the alveolar flap (/ɾ/) and the alveolar trill (/r/). While the former is alveolar, the latter has an alveo-palatal articulation.[10]

Kurmanji Kurdish

  • Distinguishes between aspirated and unaspirated voiceless stops, which can be aspirated in all positions. Thus /p/ contrasts with /pʰ/, /t/ with /tʰ/, /k/ with /kʰ/, and the affricate /t͡ʃ/ with /t͡ʃʰ/.[2][8][11]
  • Although [ɥ] is considered an allophone of /w/, some phonologists argue that it should be considered a phoneme.[12]

Sorani Kurdish

Southern Kurdish

  • [ɲ] is an allophone of /n/, occurring in the about 11 to 19 words that have the consonant group ⟨nz⟩. The word yânza is pronounced as [jɑːɲzˠa].[16]


  • Kurdish has labialized counterparts to the velar plosives, the voiceless velar fricative and the uvular stop. Thus /k/ contrasts with /kʷ/, /ɡ/ with /ɡʷ/, /x/ with /xʷ/, and /q/ with /qʷ/.[17] These labialized counterparts do not have any distinct letters or digraph. Examples are the word xulam ('servant') which is pronounced as [xʷɪˈlɑːm], and qoç ('horn') is pronounced as [qʷɨnd͡ʒ].[18]


  • After /ɫ/, /t/ is palatalized to [tʲ]. An example is the Central Kurdish word gâlta ('joke'), which is pronounced as [gɑːɫˈtʲæ].[8]
  • /k/ and /ɡ/ are strongly palatalized before the front vowels /i/ and /e/ as well as [ɥ], becoming acoustically similar to /t͡ʃ/ and /d͡ʒ/.[2]
  • When preceding /n/, /s, z/ are palatalized to /ʒ/. In the same environment, /ʃ/ also becomes /ʒ/.[19]


  • In some cases, /p, t, k, s, z/ are pharyngealized to [pˤ, tˤ, kˤ, sˤ, zˤ]. For example, the word sed/ṣed is pronounced as [ˈsˤɛd][8][4][20]
  • Furthermore, while [fˤ] and [ɡˤ] are unique to Central Kurdish,[5] Kurmanji has [t͡ʃˤ].[21]

Facultative consonants

  • /ɣ/ is a non-native phoneme that is almost exclusively present in words of Arabic origin. Even though it can be replaced by /x/ respectively, it is facultative. Thus the word xerîb/ẍerîb ('stranger', /ɣɛˈriːb/) as either [xɛˈriːb] or [ɣɛˈriːb].[22]
  • /ʕ/ is only present in words of Arabic origin and is present mostly in initial position.[23]
  • /ʔ/ is mainly present in Arabic loan words and affect the pronunciation of that vowel. However, many Kurds avoid using the glottal phoneme for nationalist and purist reasons since the glottal phoneme is seen as the embodiment of Arabic influence in Kurdish.[24]


The vowel inventory differs by dialect, some dialect having more vowel phonemes than others. /iː, ʊ, uː, ɛ, eː, oː, ɑː/ are the only vowel phonemes present in all three Kurdish dialects.

Detailed table

Letter Phoneme
Kurmanji[27] Central[28] Southern[29][30]
a ɑː a a[31]
â ɑː ɑː[32]
e ɛ ɛ ɛ
i ɪ ɪ ɨ[33]
o o
ö øː[34]
u ʊ ʊ ʊ[35]
ü ʉː[36]


  • In Central Kurdish, /a/ is realized as [æ], except before /w/ where it becomes mid-centralized to [ə]. For example, the word gawra ('big') is pronounced as [ɡəwˈɾæ].[37]
  • /ɪ/ is realized as [ɨ] in certain environments.[26][38][39]
  • In some words, /ɪ/ and /u/ are realized as [ɨ]. This allophone occurs when ⟨i⟩ is present in a closed syllable that ends with /m/ and in some certain words like dims ('molasses'). The word vedixwim ('I am drinking') is thus pronounced as [vɛdɪˈxʷɨm],[38] while dims is pronounced as [dɨms].[40]

Facultative vowels

  • /øː/ only exists in Southern Kurdish, represented by ⟨ö⟩. In Kurmanji, it is only present facultatively in loan words from Turkish, as it mostly merges with /oː/. The word öks (from Turkish ökse meaning 'clayish mud') is pronounced as either [øːks] or [oːks].[41]

Glides and diphthongs

The glides [w], [j], and [ɥ] appear in syllable onsets immediately followed by a full vowel. All combinations except the last four are present in all three Kurdish dialects.
