Ghunnah in Tajweed: Meaning, Letters, Counts and Rules

Ghunnah is the nasal sound of Noon and Meem. Ghunnah is the nasal sound of Noon and Meem. In Tajweed, it is held for 2 counts in 6 fixed situations, and it stays short and light everywhere else. 

Most learners know the definition. The trouble starts in practice. According to a study by Surul Shahbudin Hassan and Muhammad Azhar Zailaini of the International Islamic University Malaysia (IIUM) and the University of Malaya, 20 university students made 1,662 Tajweed errors while reciting about 2.5 pages of the Mushaf. That is 83 errors per student. Ghunnah errors made up 379 of them, or 23% of the total.

The same 4 problems appear again and again:

• Cutting the nasal sound short on a doubled Noon or Meem.
• Hiding the Noon wrongly in Ikhfa, or not hiding it at all.
• Adding ghunnah where the rule removes it, such as before Lam and Raa.
• Thinning the ghunnah before a heavy letter like Qaf.

This guide answers each question in order. It defines ghunnah, names its letters, locates the khayshum, and gives the measured length of 2 counts. It then maps the 6 rules that require a full ghunnah, the rules that remove it, its heavy and light forms, its 5 levels, and the Mushaf marks that signal it.

What Does Ghunnah Mean in Tajweed?

Ghunnah (غُنَّة) is a resonant nasal sound that comes from the khayshum and is built into the letters Noon and Meem. It is a permanent characteristic of both letters, so it never fully leaves them.

Tajweed scholars define ghunnah on 2 levels:

1. Linguistic meaning: According to a Tajweed lecture by Dr. Qais Abdullah Ahmed at Mustansiriyah University, ghunnah in Arabic means a sound from the khayshum.
2. Technical meaning: The same lecture defines it as a sound from the far end of the nose in which the tongue plays no role. Modern Arabic Tajweed references add that it is a pleasant, resonant sound fixed in Noon and Meem. 

Scholars of recitation describe ghunnah as a sound bound to Noon and Meem by origin and by circumstance, as long as their articulation point does not shif. This is why Tajweed books call it a “sifah lazimah”, an inseparable characteristic.

What do the classical Tajweed poems say about ghunnah?

The 2 most taught Tajweed poems both state the rule of ghunnah directly:

• Tuhfat al-Atfal by Sulayman al-Jamzuri (1198 AH), line 17: وَغُنَّ مِيمًا ثُمَّ نُونًا شُدِّدَا ۝ وَسَمِّ كُلًّا حَرْفَ غُنَّةٍ بَدَا. Meaning: apply ghunnah to Meem and Noon when doubled, and call each one a letter of ghunnah.
• Al-Muqaddimah al-Jazariyyah by Ibn al-Jazari (833 AH): وَأَظْهِرِ الْغُنَّةَ مِنْ نُونٍ وَمِنْ ۝ مِيمٍ إِذَا مَا شُدِّدَا. Meaning: make the ghunnah of Noon and Meem clear when they are doubled.

Both texts tie the full ghunnah to the Shaddah. The IIUM study above lists the works of Al-Jazari and Al-Jamzuri as its main reference sources for judging recitation errors.

Which Letters Carry Ghunnah?

Ghunnah belongs to 2 letters only:

1. Noon (ن)
2. Meem (م)

Tanween carries ghunnah too, because every Tanween is an unwritten Noon Sakinah pronounced at the end of a noun. 

Arabic Tajweed teaching material lists the letters of ghunnah as Noon and Meem, with no third letter. According to phonetics references, [m] and [n] are nasal consonants produced with a lowered velum, so air escapes through the nose, and both rank among the most common sounds across human languages.

The mouth position changes between Noon and Meem. The nasal source stays the same. Other letters next to Noon or Meem gain no ghunnah of their own.

Where Is the Khayshum, and How Does It Produce Ghunnah?

The khayshum (الخَيْشُوم) is the nasal passage that connects the upper part of the nose to the upper throat. It is the articulation point of ghunnah, and it is 1 of the 5 main articulation areas in Tajweed. 

According to the Mustansiriyah University Tajweed lecture, the khayshum is the fifth articulation area, and the letters of ghunnah emerge from it in 4 cases: Noon Sakinah and Tanween with Idgham with Ghunnah, Ikhfa and Iqlab, doubled Noon and Meem, and Meem Sakinah merged or hidden before Meem and Baa.

Speech science describes the same mechanism in anatomical terms:

• Velum position: The Interdisciplinary Speech Research Lab at the University of British Columbia reports that the velum stays raised in most speech and closes the nasal passage. Speakers lower it to produce nasal sounds.
• Resonance source: The Department of Linguistics at Macquarie University states that nasal consonants such as /m/ and /n/ consist of nasal cavity resonances, while the closed mouth acts as a side chamber.
• Blocked nose test: Phonetics references note that a congested nose turns nasal stops into oral stops, so [m] sounds closer to [b].

This gives a simple self-check. Pinch the nose gently during the ghunnah of إِنَّ. A correct ghunnah stops at once. A sound that continues is coming from the mouth, not the khayshum.

How Many Counts Is Ghunnah?

A full ghunnah lasts 2 counts (2 harakat) in the Hafs 'an 'Asim recitation through the Shatibiyyah route. One count equals the length of 1 short vowel at the reciter's own pace, so the count is relative, not a fixed number of seconds.

The Mustansiriyah University lecture states that ghunnah is held for 2 harakat in its 3 strongest levels and stays a short, natural sound in the 2 weaker levels. Arabic Tajweed scholarship adds that the difference between the 3 strongest levels is strength, not time, because all 3 last 2 harakat.

How long is 2 counts in seconds?

A complete ghunnah measured 0.66 to 1.23 seconds across 10 professional Quran reciters. Ammar Mohammed, Mohd Shahrizal Sunar and Md Sah Hj Salam recorded these values in a 2017 Springer study on recognising Tajweed rules by phoneme duration.

The slowest reciter held ghunnah almost twice as long as the fastest one. Both were correct, because each reciter kept 2 counts at his own pace. A stopwatch target of "2 seconds" is therefore inaccurate. The correct measure is the reciter's own short vowel.

How do you practise a steady 2-count ghunnah?

A steady ghunnah comes from matching the teacher's pace, then keeping the nasal sound continuous. These 5 steps build that control:

1. Listen to a teacher recite إِنَّ (2:153) at a medium pace.
2. Repeat the word while closing 2 fingers, one per count.
3. Keep the sound unbroken between the 2 finger movements.
4. Record the attempt and compare it with the teacher's model.
5. Remove the finger aid once the timing holds inside full verses.

The IIUM study recorded 3 timing errors where students held ghunnah longer than 2 counts, against 51 errors of a doubled Noon held too short. Short ghunnah is the larger problem by a ratio of 17 to 1.

Which Tajweed Rules Require a Full 2-Count Ghunnah?

There are 6 situations that require a full 2-count ghunnah: Noon and Meem Mushaddad, Idgham with Ghunnah, Iqlab, Ikhfa Haqiqi, Ikhfa Shafawi and Idgham Shafawi. Each one starts from a Noon or Meem and depends on the letter that follows.

The table maps each rule to its trigger and a Quran example. All 6 rules hold the ghunnah for 2 counts.

Ikhfa Haqiqi fails in 2 distinct ways. The IIUM study counted 73 errors of not hiding the Noon and 45 errors of cutting its 2 counts short, so concealment and timing need separate practice.

What are the 15 letters of Ikhfa Haqiqi?

The 15 letters of Ikhfa Haqiqi are ت ث ج د ذ ز س ش ص ض ط ظ ف ق ك. Al-Jamzuri encoded them in the first letters of one line of Tuhfat al-Atfal: صِفْ ذَا ثَنَا كَمْ جَادَ شَخْصٌ قَدْ سَمَا ۝ دُمْ طَيِّبًا زِدْ فِي تُقًى ضَعْ ظَالِمَا. During Ikhfa, the tongue moves toward the next letter while the ghunnah continues for 2 counts. 

What is the difference between complete and incomplete Idgham?

Complete Idgham (Idgham Kamil) happens before ن and م: the Noon disappears fully into the next letter. Incomplete Idgham (Idgham Naqis) happens before و and ي: part of the Noon's ghunnah remains during the merge. Arabic Tajweed references rank Idgham Naqis as the second level of ghunnah, below the doubled letter, with مِن وَرَائِهِمْ as an example.

When Does Ghunnah Disappear or Stay Short?

Ghunnah stays short in 4 situations and disappears completely in 1. The short cases keep only the natural nasal quality of Noon and Meem, with no 2-count hold.

Why is there no Idgham inside one word?

Noon Sakinah followed by و or ي inside 1 word stays clear, because merging it would make the word sound like a doubled root and change its form. Tuhfat al-Atfal names this exception and its examples, الدُّنْيَا and صِنْوَانٌ .

Which mistake adds ghunnah where it does not belong?

The IIUM study logged 25 errors of adding ghunnah where the rule has none, such as nasalising Meem Sakinah in Izhar Shafawi. A related pattern appears before Lam and Raa. Learners who practise ي ن م و with a full hum often carry the same hum into مِّن رَّبِّهِمْ, where Hafs removes it.

How Can You Spot Ghunnah in the Mushaf?

The Madinah Mushaf marks ghunnah with 4 visual signals: a Shaddah on Noon or Meem, a missing Sukoon on Noon Sakinah, staggered Tanween, and a small Meem for Iqlab. Each signal tells the reader to apply a 2-count ghunnah before reading the next letter.

The Tanzil Project notes that the Madinah Mushaf writes Tanween sequentially in cases of Idgham and Ikhfa. A 2017 Unicode proposal by Eric Muller records 3 distinct Tanween signs in Quranic print, ordinary, open and Meem Tanween, each one tied to a different pronunciation. Tajweed teaching material confirms that a small standalone Meem marks the position of Iqlab.

The Sukoon pattern is visible in the Tanzil Uthmani text itself. The Noon in مَنْ آمَنَ carries a Sukoon, while the Noon in مِن قَبْلِكَ and فَمَن يَعْمَلْ carries none.

Which practical fixes target the most common ghunnah errors?

Each common error has a direct practice fix:

1. Pinch the nose during إِنَّ to confirm the sound comes from the khayshum.
2. Count 2 finger movements on every Shaddah over Noon or Meem.
3. Shape the tongue toward the next letter during Ikhfa, without touching the Noon point.
4. Raise the back of the tongue before ص ض ط ظ ق to keep the ghunnah heavy.
5. Drop all nasal hold before ل and ر in Idgham without Ghunnah.
6. Record 1 page a week and compare it with a teacher's recitation of the same page.
