The Arabic letter "ن" (noon) is written with a backwards "n" when it appears at the beginning of a word or at the beginning of a syllable.
Here's a breakdown:
* Isolated form: ن (looks like a backwards "n")
* At the beginning of a word or syllable: ن (still looks like a backwards "n")
* In the middle of a word: ن (looks more like a "n" with a tail)
* At the end of a word: ن (looks like a "n" with a tail)
The letter's shape changes depending on its position within a word, but its base form, and the most common way it's written, is indeed with a backwards "n".
