Question: what is tanwin in arabic?
Answer: In some Semitic languages, such as Literary Arabic, nunation (Arabic: تَنوِين‎ tanwīn) is the addition of one of three vowel diacritics (Arabic: حَرَكَات‎ ḥarakāt) to a noun or adjective to indicate that the word ends in an alveolar nasal without the addition of the letter nūn.
