The Gateway to Arabic series is a well-structured, progressive course designed to teach Arabic to non-Arabic speakers of all ages. As students learn, they develop their knowledge of Arabic grammar and vocabulary, applying these skills in written exercises, conversations, and reading comprehension. Gateway to Arabic Book Four builds on the knowledge of the first form of regular past and present tense verbs from Book Three by introducing hollow, double root, and hamza verb forms. Furthermore, the book deepens knowledge of ordinal and cardinal numbers and their associated rules, and teaches the use of numerals to indicate time and count.
