The main purpose of the article is to introduce what styles a speaker can use to express his opinion. “Speech” is considered the most important factor in expressing an idea. The structure of sentences is actually studied in grammar, but the meanings expected from them are not considered a subject of grammar; this issue is analyzed in the science of stylistics. In the science of meaning, there are three ways of expressing thoughts: ijaz, itnab and musawa. The speaker must express his purpose according to the listener's situation. If he expresses his opinion briefly and succinctly, then it is called “ijaz”, and if he expresses it in detail, then it is called “itnob”. This article provides information about the concept of “itnob” and its use, which is one of the unique ways of expressing thoughts in Arabic style. The article was written using comparative historical, comparative typological, systemic structural, and descriptive methods.
