These days a teacher who makes students diagram sentences is quite rare. Learning any foreign language forces us to look at our own grammar structures. This is particularly true regarding Arabic because the written language includes certain symbols that one must write at the ends of words which mark their syntax and provide other information. The grammar has rules and exceptions to the rules that even some Arabs find tedious. However, many of the rules are based on logic that is understandable.
Pronunciation can be a challenge at first.
Arabic contains ten sounds that do not exist in English. Some letters are rather harsh sounding to Americans and make some people reluctant to pronounce them. It takes practice to master them. Some students have recommended practicing in front of a mirror in the privacy of one s own home. Certain aspects of the language do exist that make it an easy one to learn.
