There are 28 basic letters. All of them are cursive, both in handwriting and in print. This means that inside a word, a letter is usually directly connected to the letter following it. Arabic is written from right to left. Each letter can have up to 4 different forms. Which of the forms is used depends on the letters before and after it. The form for uppercase letters and lowercase letters is the same.
The alphabet can also be used to write numbers. This was common in the Middle Ages. Today it can be found more rarely. Usually, Latin-alphabet (Arabic) numbers are used.
Another usage that is rare today, is to use the letters of the alphabet to stand for numbers. That way, the letter ʼalif is 1, ب bāʼ is 2, ج ǧīm is 3, and so on until ي yāʼ = 10, ك kāf = 20, ل lām = 30, …, ر rāʼ = 200, …, غ ġayn = 1000. This is sometimes used to produce chronograms.
