The Arabic script is a writing system used for writing several languages of Asia and Africa, such as Arabic, Persian, Pashto and Urdu. Even until the 16th century, it was used to write some texts in Spanish. After the Latin script, it is the second-most widely used writing system in the world.
The Arabic script is written from right to left in a cursive style. In most cases the letters transcribe consonants, so most Arabic alphabets are classified as abjads.
The script was first used to write texts in Arabic, most notably the Qurʾān, the holy book of Islam. With the spread of Islam, it came to be used to write languages of many language families, leading to the addition of new letters and other symbols, with some versions, such as Kurdish and Uyghur being abugidas or true alphabets. It is also the basis for a rich tradition of Arabic calligraphy.
The Arabic script has the ISO 15924 codes Arab and 160.
