Traditional Arabic letters are the characters used in the Arabic script, which is written from right to left. The Arabic alphabet consists of 28 letters, each representing a consonant sound. Vowel sounds are indicated using diacritics, which are small marks placed above or below the letters. The letters can take different forms depending on their position in a word—initial, medial, final, or isolated. The Arabic script is used in various languages, including Arabic, Persian, and Urdu. It is known for its beautiful calligraphy, which is an important art form in Islamic culture. Traditional Arabic letters are not only functional for writing but also serve as a means of artistic expression.
