Find and enroll in an Arabic course appropriate for you. Decide whether you want a classroom or an online course. Some language-learning companies offer free online courses, while others charge a small fee. Several universities, such as New York University, offer in-person Arabic classes for adults and children.
Study diligently. Acquiring fluency in a non-native language takes time and practice. You must study grammar, vocabulary and syntax often in order to build up fluency. Come to class prepared, or complete online class assignments according to schedule.
Practice speaking as often as you can. Find opportunities to practice the Arabic you learn in your course. Listen to suggestions on pronunciation and grammar. Speaking the language aloud will make it easier for you to recall words and use key phrases.
