Kurdish is spoken by 40 million people throughout the world and is mostly spoken in Turkey, Iraq, Iran, Syria, and Germany. The majority of Kurdish people are practicing Sunni Muslims. Kurds have never received nation-state status, making it one of the largest stateless regions in the world. There are three unique dialects within Kurdish that have their own writing systems. Kurmanii is written in the Latin script like Turkish. Sorani is written in Perso-Arabic script. Pehlewani is written in either script. Understanding Kurdish Speech and Language Development will aid in a deeper appreciation for the Kurdish Language and will help educators support Kurdish-speaking students who are learning English.
For the purposes of this page, we will be focusing on Kumanji, as it is the most widely spoken of these dialects. Kurdish belongs to the language families of Indo-European, Indo-Iranian, Iranian, Western, and Northwestern. Kurdish is the official language of Iraq, Kurdistan Region, and Rojava. Iraq has multiple official languages, so Kurdish is just one of them. This page will focus on the unique characteristics of Kurdish. We will compare the different phonemes in Kurdish and English, discuss phonotactic constraints of Kurdish, and compare the language differences between Kurdish and English.
Interesting Facts About Kurdish Speech and Language Development
- The Kurds are one of the largest ethnic groups in the world without an independent nation, with an estimated 30 to 40 million people spread across several countries.
- Kurdistan is a cultural and geographic region that spans across parts of Turkey, Iraq, Iran, and Syria, with smaller communities in Armenia and elsewhere.
- In Iraq’s autonomous Kurdistan Region, Kurdish is an official language alongside Arabic and is used in schools, media, and government.
- There are three separate dialects within Kurdish. Kuramnii is the most common with 20 million native speakers. Other dialects are Sorani and Pehlewani.
- Kurdish hospitality is famous, and it is common for guests to be offered tea, sweets, and a meal regardless of the time of day.
- The word “Kurdistan” means “Land of the Kurds” and has been used for centuries to describe the mountainous homeland of the Kurdish people.
Understanding Kurdish Dialects in Clinical Practice
Kurdish is not a single, unified language but rather a dialect continuum comprising several varieties that differ significantly in phonology, grammar, and vocabulary. The two most widely spoken dialects are Kurmanji (Northern Kurdish) and Sorani (Central Kurdish), followed by smaller groups such as Pehlewani, Zazaki, and Gorani. Among these, Kurmanji is the most widely spoken Kurdish dialect, used by an estimated 15–20 million speakers, primarily across Turkey, Syria, northern Iraq, and parts of Iran. Sorani, while spoken by fewer people (about 8–10 million), holds official status in the Kurdistan Region of Iraq and is widely used in Kurdish media, education, and government.
Importantly for clinical professionals, Kurmanji and Sorani are not mutually intelligible. This means that speakers of one dialect may not understand the other without prior exposure or learning. The phonological, grammatical, and even script differences between these dialects are substantial. For example, Sorani uses a modified Arabic script, while Kurmanji is written in a Latin-based script. These distinctions have real implications for speech and language assessment.
For speech-language pathologists working with Kurdish-English bilingual children, it is essential to determine which dialect the child speaks at home. If an interpreter is needed for evaluation or family interviews, the interpreter must be fluent in the specific Kurdish dialect spoken by the family. Using an interpreter of the wrong dialect could result in misunderstandings, inaccurate assessments, and a breakdown in rapport.
Sorani (Central Kurdish)
- Region: Primarily spoken in Iraq (Kurdistan Region) and Iran (Kurdish areas of Kermanshah and Sanandaj).
- Alphabet: Uses a modified Arabic script.
- Grammar:
- Analytic: Relies more on word order and function words than inflection.
- No case system like Kurmanji.
- Phonology: Includes pharyngeal and uvular sounds, like /ʕ/, /ħ/, /q/, /x/.
- Example word: کوردی (Kurdî – “Kurdish” in Sorani)
Kurmanji (Northern Kurdish)
- Region: Predominantly spoken in Turkey, Syria, parts of Iraq and Armenia.
- Alphabet: Uses a Latin-based script.
- Grammar:
- Inflected: Retains grammatical gender, case marking, and verb conjugations that are more synthetic.
- Has ergative alignment in past tense.
- Phonology: Some consonants (like /ɫ/ and /ʁ/) appear in Kurmanji but not Sorani.
- Example word: Kurdî (same word, different script: Kurdî – “Kurdish” in Kurmanji)
Key Differences
| Feature | Sorani | Kurmanji |
|---|---|---|
| Alphabet | Arabic-based | Latin-based |
| Region | Iraq, Iran | Turkey, Syria, Armenia |
| Grammar | No case system | Has nominative/oblique cases |
| Phonology | Has /ʕ/, /ħ/, /q/, /x/ | Has /ɫ/, /ʁ/, /q/ |
| Use in Education | Official in Kurdistan Region, Iraq | Used more in diaspora and Turkey |
In summary, Sorani is a dialect and is not mutually intelligible with Kurmanji. Therefore we provided separate consonant and vowel tables below.
Sorani Kurdish Speech and Language Development
Sonrani Kurdish Consonants in Comparison to English
| Sonrani Kurdish Consonants Not Shared with English | /q/ (voiceless uvular stop), /χ/ or /x/ (voiceless uvular/velar fricative), /ʁ/, /ħ/, /ʕ/ (pharyngeals), /ɬ/ (voiceless lateral) |
| Consonants Shared With English | /p/ /b/ /t/ /d/ /k/ /g/ /f/ /v/ /s/ /z/ /ʃ/ /ʒ/ /tʃ/ /dʒ/ /h/ /m/ /n/ /ŋ/ /j/ /l/ /r/ /w/ |
| English Consonants Not Shared with Sonrani Kurdish | /θ/ /ð/ |

Notes on Sonrani Kurdish Phonology
- Consonants: Kurdish includes uvular (/q/, /χ/) and pharyngeal (/ħ/, /ʕ/) consonants, which are not found in English; conversely, English dental fricatives (/θ, ð/) are not present in Kurdish .
- Vowels: Kurdish uses /ɔ/ but lacks the rhotic vowel /ɚ/ and lax front vowels like /I/, /ʊ/, /ʌ/ found in English .
- Diphthongs: Kurdish lacks phonemic diphthongs—they appear as vowel + glide sequences, not contrastive phonemes; English has eight distinct diphthongs.
- Kurdish has eight vowels; English has twelve; English diphthongs are also absent as phonemes in Kurdish.
Kurmanji Kurdish Speech and Language Development
Kurmanji Kurdish Consonants in Comparison to English

| Vowels Shared With English | /a/ (or /ɑː/) /æ/ /e/ /i/ /ɪ/ /o/ /u/ /ʊ/ /ə/ |
| English Vowels Not Shared with Kurmanji Kurdish | /ɚ/ (rhotic-stressed vowel), /ʌ/ |
Notes on Kurmanji Kurdish Phonology
- Stops: Unlike English, Kurmanji distinguishes aspirated vs. unaspirated stops—this contrast is phonemic (e.g., /pʰ/ vs. /p/).
- Pharyngeals and labio‑velars: Pharyngeal sounds (/ʕ/) and complex labio‑velars (/kw/, /gw/, /xw/) exist in Kurmanji but not in English.
- Vowel length: Long vs. short vowels are phonemic in Kurmanji, augmenting distinctions English lacks.
- Allophony: Single orthographic letters may correspond to multiple real vowel sounds (e.g., “e” → /æ/, /ɛ/, or /ə/) .
- Shared phonemes: Many core consonants and vowels overlap with English phonemic inventories.
The Use of Phonotactic Constraints in Kurdish Speakers
1. Syllable Structure
- Kurdish syllables typically follow the template: (C) CV (C)(C)(C) — that is, optional onset consonant(s), a vowel nucleus, and up to three consonants in the coda (files.eric.ed.gov).
- A more restrictive real-world pattern tends to be (C) CV (C)(C)—up to two consonants both in onset and coda .
2. Onset Clusters
- Initial clusters are often limited to consonant + glide (e.g., Cw, Cj) or stop + liquid (e.g., /pl/, /bl/, /tr/) .
- More complex clusters (3+ consonants) in word-initial position are rare/uncommon (files.eric.ed.gov).
3. Coda Clusters
- End-of-syllable structures can have up to three consonants, but two-consonant codas (CC) are more frequent (pdfs.semanticscholar.org).
- Triple-consonant codas (CCC) do occur in some contexts (e.g., borrowed or compound words), though less common .
4. Consonant Restrictions
- Certain consonants like /ɫ, r, ŋ/ rarely or do not appear in coda position (jgu.garmian.edu.krd).
- Obstruents (stops/fricatives) rarely cluster before other obstruents in coda unless phonemically permitted (pdfs.semanticscholar.org).
5. Vowel Epenthesis
- When English-style consonant clusters are borrowed or approximated, Kurdish speakers may insert a vowel (e.g., /strict/ → /setrict/ or /estrict/) (journals.aiac.org.au).
6. Deletion & Assimilation
- Kurdish exhibits final or medial consonant deletion in casual speech (especially /d/ or /t/) in specific morphological contexts (kurdishacademy.org).
- This deletion sometimes triggers nasal assimilation; e.g., /pend/ (“proverb”) → /peŋ/ (kurdishacademy.org).
7. Sonority-Based Sequencing
- Kurdish adheres to the sonority sequencing principle: more sonorous sounds (vowels > glides > liquids), must be centrally placed in syllables, with less sonorous consonants framing them (en.wikipedia.org).
Kurdish Speech Developmental Norms
| Age of Acquisition | Sounds |
|---|---|
| By 3;0 years | All vowels are typically acquired. (pubmed.ncbi.nlm.nih.gov) |
| By 4;6 years (4 years 6 months) | Nearly all consonants in initial, medial, and final positions are acquired, with exceptions: initial /ʤ/, medial /ɣ/, and final /ʒ/, /z/, /g/, /ɣ/. |
| By 4;0 years | Most consonants are phonologically accurate (errors minimal to none), except for the sounds noted above. |
Kurdish Developmental Norms Summary
- Kurdish-speaking children typically produce all vowels by age 3.
- By around 4½ years, most consonants in all word positions are produced accurately.
- The following sounds are later to acquire:
- /ʤ/ (as in “judge”) — initial position
- /ɣ/ (voiced velar fricative) — medial position
- /ʒ, z, g, ɣ/ — final position (pubmed.ncbi.nlm.nih.gov, sciencedirect.com)
- Accuracy improves with age, and no gender differences were observed in acquisition (pubmed.ncbi.nlm.nih.gov).
Language Specific Differences Between English and Kurdish
English and Kurdish (both Sorani and Kurmanji dialects) differ in several key grammatical areas, which impact bilingual development and language assessment. Kurdish follows a Subject–Object–Verb (SOV) structure, unlike English’s Subject–Verb–Object (SVO), and places adjectives and possessives after the noun they modify, whereas English places them before. Kurdish uses suffixes to mark articles, possession, definiteness, and plurality—English uses separate words. Kurdish also exhibits split-ergative verb alignment and rich inflectional verbal morphology, compared to English’s relatively simpler tense and aspect system.
Comparison Table of Language Features
| Language Features | Kurdish | English |
|---|---|---|
| Sentence Word Order | SOV (e.g., “I book read”) (en.wikipedia.org) | SVO (“I read a book”) |
| Adjectives/Noun Modifiers | Adjective follows noun, linked via Ezafe or suffix | Precede nouns (“a red ball”) |
| Possessives | Expressed with suffix after noun (“mala min” = “house-my”) | Precede noun, separate word (“my house”) |
| Possessive Pronouns | Enclitic pronouns attached to nouns or verbs | Independent pronouns (“mine”, “yours”) |
| Verb Inflection | Complex; marks subject, object, tense, aspect; split-ergative in past for transitive verbs | Simpler: regular/irregular forms, auxiliaries, auxiliaries for tense-aspect |
| Pronouns | Independent + bound pronouns; subject often omitted | Independent pronouns required |
| Pronoun Gender | No grammatical gender distinctions in pronouns | No gender distinctions except third-person singular “he/she/it” |
| Subjects of Sentences | Often omitted (pro-drop); subject marked on verb | Subject required |
| Regular Past Tense | Tense expressed via verbal suffixes and auxiliary forms | -ed endings; consistent pattern |
| Irregular Past Tense | Irregular stems exist; marked via suffixes | Irregular forms (e.g., “went”, “saw”) |
| Negatives | Negation prefix “na-” or “naw-” on verb | “do not” + base verb |
| Double Negatives | Allowed or neutral (“na…na”) | Generally nonstandard in standard English |
| Question Formation | Word order unchanged (SOV), question particles used | Inversion of auxiliary and subject |
| Definite Articles | Suffix -eke/-kan (Sorani) after noun | “the” |
| Indefinite Articles | Suffix -êk/-ek after noun | “a, an” |
| Prepositions | Postpositions or circumpositions used after noun phrases | Prepositions before noun phrases |
| Present Progressive Verb Form | Expressed via aspectual prefix + verb (e.g., “dexom”) | “am/is/are + verb-ing” |
| Modal Verbs | Less modular; expressed via auxiliary verbs and morphological inflection | “can, may, must, will” auxiliary verbs |
| Copula/”To Be” Verbs | Expressed via “bûn” or suffix; often omitted in present | “to be” required (“is, am, are”) |
| Auxiliary Verbs | Used for perfect, passive, etc., via auxiliaries plus main verb | “do, have, be” as auxiliaries |
| Passive Voice | Passive formed with “hatin” and past participle | “be + past participle” |
| Direct Object Pronouns | Enclitic pronouns attached to verb for object | Separate pronouns placed after verb |
| Conjunctions | Single conjunction particles (e.g., “û” for “and”) | “and, but, or” |
| Plurals | Suffix -an/-kan/yan; no vowel change | Suffix “-s” or “-es” |
