Tanween is a doubled vowel mark at the end of a word — it adds an “n” sound, so a word ending in Fatha becomes “an”, in Kasra becomes “in”, and in Damma becomes “un”. It looks like a small detail, and it is — but it changes how a word sounds, and it is one of the first Tajweed rules you meet.
Key takeaways
- Tanween is a doubled vowel at the end of a word — it adds an “n” sound.
- There are three forms: Fatha becomes “an”, Kasra becomes “in”, Damma becomes “un”.
- Tanween only appears at the end of words, and it is really a hidden Noon.
- It matters for Tajweed, because what follows the Tanween decides how it is read.
What tanween is, and the three forms
Tanween is a vowel mark written at the end of a word. It is the short vowel doubled: instead of one Fatha, you write two; instead of one Kasra, two; instead of one Damma, two. And that doubling adds an “n” sound to the end of the word.
There are three forms, matching the three short vowels.
Tanween with Fatha — two Fatha marks — gives an “an” sound at the end of the word. Tanween with Kasra — two Kasra marks — gives an “in” sound. Tanween with Damma — two Damma marks — gives an “un” sound. Three forms, three sounds, and the pattern is the same every time: the vowel, plus “n”.
A useful way to think about Tanween is that it is really a hidden Noon. The “n” sound you hear is the sound of the letter Noon, even though no Noon is written. That is why Tanween behaves like a Noon Sakinah (a still Noon) in the rules of Tajweed — because, in sound, that is what it is.
How to spot tanween in the Mushaf
Tanween is easy to spot once you know what to look for: it is the doubled mark at the end of a word.
For Fatha Tanween, you will see two small diagonal strokes above the final letter — sometimes written side by side, sometimes one above the other, depending on the Mushaf. For Kasra Tanween, two small strokes below the final letter. For Damma Tanween, two small curls above the final letter — sometimes written as a curl with a small mark beside it.
Tanween only ever appears at the end of a word. You will never find it in the middle of a word, because it is a word-ending sound. That is the quickest way to recognise it: a doubled vowel mark, at the end of a word, is Tanween.
It appears constantly in the Quran — on nouns, most often — so once you learn to spot it, you will see it on almost every page. Your teacher will point it out in your reading until recognising it becomes automatic.
How tanween sounds in real words
The sound of Tanween is simple: the vowel, plus “n”, held for a short moment.
With Fatha Tanween, the word ends in “an” — the short “a” sound, followed by a light “n”. With Kasra Tanween, it ends in “in” — the short “i” sound, followed by “n”. With Damma Tanween, it ends in “un” — the short “u” sound, followed by “n”. In each case, the “n” is light and quick, not heavy or held.
The most important thing is not to overdo it. Tanween is a short sound, not a long one — the “n” is there, but it is not stretched. A beginner who holds the “n” too long changes the rhythm of the word, and a beginner who drops it entirely loses the Tanween altogether. The right sound is in between: a clear, light “n”, for about the same length as the vowel itself.
The way to learn it is by reading words aloud with your teacher. Your teacher will say a word with Tanween, you will repeat it, and the teacher will correct the length of the “n” until it is right. A few sessions of this, and the sound becomes natural.
Mufti Menk’s teaching stresses the same point about small marks like Tanween: the Quran is meant to be heard and read aloud, not only studied silently, and correct pronunciation is the first step. A mark as small as Tanween is part of getting the sound right — and getting the sound right is what makes the reading correct.
Tanween and the Noon Sakinah rules — why it matters for Tajweed
Tanween matters beyond its own sound, because it is treated exactly like a Noon Sakinah in the rules of Tajweed. That is the reason it is taught carefully: what you do with Tanween depends on the letter that follows it.
There are four rules, and the next letter decides which one applies. If the next letter is one of the six throat letters, the Tanween is pronounced clearly — this is called Izhar. If the next letter is one of the six merging letters, the Tanween melts into it — this is Idgham. If the next letter is Ba, the Tanween turns into a Meem sound — this is Iqlab. And if the next letter is one of the fifteen remaining letters, the Tanween is hidden with a nasal sound — this is Ikhfa.
You do not need to memorise these four rules now. They are covered in full in the Tajweed articles — “Noon Sakinah Rules Explained” gives the complete picture. What matters at this stage is understanding why Tanween is more than just a sound: because it behaves like a still Noon, it is governed by the same rules, and those rules are a central part of Tajweed. Learning Tanween properly is the first step into those rules.
Common tanween mistakes
Four mistakes come up again and again with Tanween, and all four are easy to fix.
The first is dropping the “n” entirely — reading the word as if it ended in a plain vowel. This usually happens when a student is reading quickly and does not notice the doubled mark. The fix is to slow down and check the end of each word for a doubled mark before moving on.
The second is holding the “n” too long. A student who has just learned Tanween sometimes stretches the “n” as if it were a long vowel. The fix is to keep it short and light — the same length as the vowel itself.
The third is confusing Tanween with a long vowel. A word ending in a doubled Fatha is not the same as a word ending in a long “aa” — the sounds are different, and so is the meaning. The fix is to listen carefully: Tanween ends in “n”; a long vowel does not.
The fourth is forgetting that Tanween changes with the next letter. A student who has learned the “an” sound may read it the same way every time, without noticing that the next letter changes how it should be read under the Tajweed rules. The fix is to learn the four rules in time — and to know that they exist, even before you have mastered them.
Quick practice drills
Here are three drills your teacher may use, and that you can practise between lessons.
Drill one: read words with one form of Tanween at a time. Start with Fatha Tanween only — read a line of words ending in “an”, slowly, making the “n” light and clear. Then do the same for Kasra Tanween (“in”), then Damma Tanween (“un”). One form at a time, until each sound is distinct.
Drill two: read words that mix the three forms, so you practise switching between “an”, “in” and “un”. This trains the eye to check the mark before the mouth makes the sound — and that habit is the whole skill.
Drill three: read a short passage and mark every Tanween you find before reading it aloud. Circle the doubled marks, say which form each one is, and then read the passage. This turns spotting Tanween into a habit, so you notice it automatically while reading.
Keep the drills short — five minutes each is enough — and always read aloud. Tanween is a sound skill, and it is learned by hearing and saying, not by reading about it.

Frequently Asked Questions
What is tanween in simple words?
Tanween is a doubled vowel mark at the end of a word. It adds an “n” sound: a word ending in Fatha becomes “an”, in Kasra becomes “in”, and in Damma becomes “un”. It only ever appears at the end of words.
What are the three types of tanween?
The three types match the three short vowels. Tanween with Fatha gives an “an” sound, Tanween with Kasra gives an “in” sound, and Tanween with Damma gives an “un” sound. Three forms, three sounds, and the pattern is the same every time: the vowel, plus “n”.
How do you pronounce tanween?
You pronounce the vowel, then add a light, short “n” sound — “an”, “in” or “un”. The “n” should be clear but not stretched: about the same length as the vowel itself. Your teacher will correct the length until it sounds right.
Is tanween the same as noon sakinah?
Not the same thing, but closely related. Tanween is a doubled vowel mark; Noon Sakinah is a still Noon letter. But in sound, Tanween behaves exactly like a Noon Sakinah — the “n” you hear is the sound of a hidden Noon — so the same four Tajweed rules (Izhar, Idgham, Iqlab, Ikhfa) apply to both.
Where does tanween appear in the Quran?
Tanween appears at the end of words, constantly — on nouns, most often — so you will see it on almost every page of the Quran. It is one of the most common marks in the Mushaf, which is why learning to spot it and read it correctly matters so much.
How do I practise tanween?
By reading aloud, in short drills. Start with one form at a time — words ending in “an”, then “in”, then “un” — then mix the three forms, then practise spotting Tanween in a short passage before reading it. Keep each drill to about five minutes, and always read aloud so your teacher can hear and correct the sound.
