"نون" (pronounced "noon") is the Arabic letter ن, which is the 25th letter of the Arabic alphabet. It represents the sound /n/ and is used in various words across the Arabic language. The letter ن can appear in different forms depending on its position in a word: initial, medial, final, or isolated. In Arabic script, ن has a distinct shape and is often associated with the concept of "ن" (the Arabic word for "fish"). This letter is also significant in Islamic culture, as it is linked to the story of the prophet يونس (Yunus), known as Jonah in English, who is often depicted with a fish.
