What Is Tanween in the Quran?
Tanween is a doubled vowel mark placed at the end of certain Arabic words, adding a short "-n" sound: an, un, or in. It looks like a small vowel symbol written twice, and when reciting, it's treated exactly like a noon sakinah, meaning the same four rules apply depending on which letter comes next.
Key Takeaways
- Tanween is a doubled vowel mark at the end of a word, producing an -an, -un, or -in sound.
- There are three tanween marks: fathatan, dammatan, and kasratan, matching the three short vowels doubled.
- Tanween usually signals that a noun is indefinite in Arabic grammar, similar to how "a" or "an" works in English.
- For recitation purposes, tanween behaves exactly like a noon sakinah, triggering the same izhar, idgham, iqlab, or ikhfa rule depending on the next letter.
- Mispronouncing tanween, or missing the rule it should trigger, is one of the most common small mistakes in everyday recitation.
What Tanween Looks Like and Sounds Like
Tanween appears as a doubled version of a short vowel mark, written above or below the final letter of a word. Instead of the usual single mark for a short vowel, you see two, and instead of just the vowel sound, you also hear a light "n" at the end. A word ending in a single fatha sounds like "-a", while the same word ending in fathatan sounds like "-an".
The Three Tanween Marks
| Mark | Name | Sound produced |
|---|---|---|
| ً | Fathatan | -an |
| ٌ | Dammatan | -un |
| ٍ | Kasratan | -in |
Why Tanween Usually Appears
In Arabic grammar, tanween most often marks a noun as indefinite, roughly similar to how English uses "a" or "an" before a noun rather than "the". This is a grammar point rather than a Tajweed one, but it helps explain why tanween shows up constantly throughout the Quran: indefinite nouns are extremely common in ordinary Arabic sentences.
Why Tanween Behaves Like Noon Sakinah
Even though tanween is written as a vowel mark rather than the letter noon, it produces the same "n" sound as a noon with no vowel (noon sakinah). Because of that, Tajweed treats them identically when it comes to how the sound interacts with whatever letter comes next in the following word. This is genuinely convenient once it clicks: learn the noon sakinah rules properly, and you've already learned the tanween rules too.
The Four Rules That Apply to Tanween
| Rule | What happens |
|---|---|
| Izhar | The -n sound is pronounced clearly, used before throat letters |
| Idgham | The -n sound merges into the following letter's sound |
| Iqlab | The -n sound converts into a light meem sound before the letter ba |
| Ikhfa | The -n sound is partially hidden with a nasal tone before most remaining letters |
Common Mistakes with Tanween
- Dropping the "-n" sound entirely, reading a tanween ending as if it were just a single short vowel.
- Applying the wrong rule for the following letter, for example pronouncing a clear izhar where an ikhfa should soften the sound instead.
- Rushing through word endings, especially in longer verses, where tanween can get swallowed if a reciter is moving too quickly.
Two of the four tanween rules have their own guides: iqlab and idgham. For the basic vowel marks tanween is built from, see our Arabic letters and punctuation guide.
How Mariam Quran Tutor Teaches This
Tanween is covered early in our Tajweed course, right alongside the noon sakinah rules, since they're learned as one connected set rather than two separate topics. For the full picture of how this fits with the other Tajweed categories, see our Tajweed rules overview. You can book a free trial lesson with no card required to hear these rules demonstrated properly.
