Arabic is typically written without vowel marks , native readers fill in the vowels from context and vocabulary knowledge. But those marks do exist, and understanding them is essential for correct reading, religious texts, children's books, poetry, and learning the language. They are called harakat (حركات) , literally "movements" , or collectively tashkil (تشكيل).
The Six Core Harakat
1. Fatha (فتحة) , ـَ
A small diagonal stroke above the letter. It produces a short "a" vowel. It is the most common haraka in Arabic.
| With tashkil | Without | Pronunciation |
|---|---|---|
| كَتَبَ | كتب | ka-ta-ba (he wrote) |
| ذَهَبَ | ذهب | dha-ha-ba (he went) |
| وَلَدٌ | ولد | wa-la-dun (a boy) |
2. Kasra (كسرة) , ـِ
A small stroke placed below the letter. It produces a short "i" vowel. In Arabic grammar, the kasra on the last letter of a noun signals it is in the genitive case (مجرور).
| With tashkil | Pronunciation | Grammatical role |
|---|---|---|
| مِن | min | Preposition "from" |
| فِي | fī | Preposition "in" |
| الكِتابِ | al-kitābi | Genitive (after preposition) |
3. Damma (ضمة) , ـُ
A small curled mark above the letter. It produces a short "u" vowel. On the last letter of a noun, it signals the nominative case (مرفوع) , subject position.
| With tashkil | Pronunciation | Role |
|---|---|---|
| الطَّالِبُ | aṭ-ṭālibu | Subject (nominative) |
| يَكْتُبُ | yak-tubu | Present tense verb |
| هُوَ | huwa | Pronoun "he" |
4. Sukun (سكون) , ـْ
A small circle above the letter. It indicates no vowel , the letter is a pure consonant. Essential for reading consonant clusters and stopping correctly at the end of words.
5. Shadda (شدة) , ـّ
Looks like a small "w" above the letter. It means the consonant is doubled , held slightly longer. It changes the meaning of a word completely:
| Word | Pronunciation | Meaning |
|---|---|---|
| عَلَمٌ | ʿala-mun | Flag / mark |
| عَلَّمَ | ʿal-la-ma | He taught (shadda on ل) |
| قَدَرَ | qa-da-ra | He was able |
| قَدَّرَ | qad-da-ra | He estimated / appreciated |
6. Tanween (تنوين)
Tanween doubles the haraka at the end of an indefinite noun, adding an "n" sound. There are three types corresponding to the three cases. Note that tanween on definite nouns is a common spelling mistake , only indefinite nouns take tanween.
| Mark | Name | Case | Example | Pronunciation |
|---|---|---|---|---|
| ـً | Tanween fath | Accusative / adverbial | كِتاباً | kitāban |
| ـٍ | Tanween kasr | Genitive | كِتابٍ | kitābin |
| ـٌ | Tanween damm | Nominative | كِتابٌ | kitābun |
When Is Tashkil Actually Used?
Modern Arabic is almost always written without tashkil. It appears in specific contexts:
- The Quran , fully vowelized to preserve exact pronunciation
- Children's books and textbooks , to help learners read correctly
- Poetry , to enforce meter and rhythm
- Dictionaries , to show correct pronunciation
- Disambiguation , when a word could be read multiple ways (قتل = he killed / was killed)
The Alef Madda (آ)
A special case: when a hamza with a fatha is followed by another fatha or alef, they merge into آ (alef with a wavy line on top called madda). It represents a long "ā" sound. For the full rules on hamza forms, see our complete guide to hamza.
| Written | Pronunciation | Meaning |
|---|---|---|
| آمَنَ | āmana | He believed |
| آكَلَ | ākala | He fed (causative) |
| قُرآن | Qur-ān | Quran |
Common Mistakes with Tashkil
| ❌ Error | ✅ Correct | Issue |
|---|---|---|
| Missing shadda: عَلَمَ (he flagged?) | عَلَّمَ (he taught) | Shadda changes meaning |
| Wrong case ending: الطَّالِبَ جاءَ | الطَّالِبُ جاءَ | Subject takes damma not fatha |
| Tanween on definite noun: الكِتابً | الكِتابُ (no tanween) | Definite nouns never take tanween |
| Sukun on a voweled letter: كَتَبْا | كَتَبا | Sukun cannot coexist with a long vowel |
FAQ
Do I need to learn tashkil to read Arabic?
For reading modern books, newspapers, and websites , no. Almost no contemporary text uses tashkil. But for the Quran, classical literature, and dictionaries, understanding it is essential.
Can tashkil really change a word's meaning?
Yes, dramatically. The word كتب without tashkil could mean "he wrote" (كَتَبَ), "write!" (اكتُبْ), "books" (كُتُبٌ), or "scribes" (كُتَّابٌ) , all from the same three letters.
How does Sahihli add tashkil?
Sahihli uses an AI language model trained on Arabic to infer the correct vowel marks from context , similar to how a native reader does it mentally. Paste any Arabic text and click Diacritics.
