Arabic diacritics are small marks placed above or below letters in the Arabic script to indicate specific sounds or pronunciation. They help clarify the meaning of words, as many Arabic words can have different meanings based on their vowel sounds. Common diacritics include the fatha, damma, and kasra, which represent short vowels. These diacritics are especially important for learners of the Arabic language, as they provide guidance on how to pronounce words correctly. In written texts, such as the Quran or educational materials, diacritics are often included to aid comprehension and ensure accurate reading.
