Ghunnah is a term in Arabic phonetics that refers to a nasal sound produced during the pronunciation of certain letters. It is an important aspect of Tajweed, the rules governing the recitation of the Quran. Ghunnah is typically associated with the letters ن (noon) and م (meem) when they are followed by specific letters, creating a nasal quality in the sound. In practice, ghunnah is characterized by a prolonged nasalization that lasts for about two counts. This technique enhances the beauty and clarity of the recitation, making it more melodious. Mastering ghunnah is essential for anyone looking to recite the Quran correctly and beautifully.
