Tashkil refers to the system of diacritics used in the Arabic script to indicate short vowels and other phonetic features. These markings help clarify pronunciation and meaning, especially in texts where the context may be ambiguous. Common diacritics include the fatha, damma, and kasra, which represent short vowel sounds. In addition to vowels, Tashkil also includes symbols for other phonetic elements, such as the sukun (indicating the absence of a vowel) and the shadda (indicating a doubled consonant). This system is particularly important in religious texts, poetry, and language learning, ensuring accurate reading and comprehension.
