The Arabic alphabet (Arabic: الأَبْجَدِيَّة العَرَبِيَّة‎‎ al-abjadīyah al-ʻarabīyah or الحُرُوف العَرَبِيَّة al-ḥurūf al-ʻarabīyah) or Arabic abjadiyah is the Arabic script as it is codified for writing the Arabic language. It is written from right to left, in a cursive style, and includes 28 letters. Originally, the alphabet was an abjad consisting only of consonants, but is now considered an "impure abjad". As with other abjads, such as the Hebrew alphabet, scribes later devised means of indicating vowel sounds by separate vowel points.

The basic Arabic alphabet contains 28 letters. Adaptations of the Arabic script for other languages added and removed some letters, as for Kurdish, Persian, Ottoman Turkish, Sindhi, Urdu, Malay, Pashto, and Malayalam (Arabi Malayalam), all of which have additional letters as shown below. There are no distinct upper and lower case letter forms.
