Arabic grammar is the set of rules that govern the structure of the Arabic language. It includes the formation of words, sentences, and phrases, focusing on aspects like verb conjugation, noun cases, and gender agreement. Understanding these rules is essential for effective communication in Arabic. One key feature of Arabic grammar is its root system, where most words are derived from three-letter roots. This allows for the creation of various related words by adding prefixes, suffixes, or changing vowels. Mastering this system helps learners expand their vocabulary and grasp the nuances of the language.
