The script is written from right to left. When it is used to write the Arabic language, the script has 28 different characters. Usually only consonants are written in an abjad. Vowels are omitted most of the time. The Arabic script is a cursive script. This means that letters of a word are joined together, both in handwriting and in print. Each letter can have up to four different forms. Which of the forms is used depends on the letters before and after it. There is no different form for uppercase letters and lowercase letters.
