Abstraction and its effect on meaning

Abstract

Grammarians have been describing the grammatical phenomena in their works, using terms that describe those phenomena, and reveal its important, and what each one distinguishes from the other. Their use was not limited to one description, but rather, they use the description according to their need for clarification. As for the term "abstractions", grammarians  used it a lot, they described many chapters of grammar by it. They have used this description by its various  forms; as (abstracted), (abstracted), (abstract) and so on. We have looked closely at the abstraction of words from one another, it turns out that there is an effect behind every abstraction that occurred in speech. I have spotted a bunch of these effects, so, I stopped at them to show their importance. Then I divided the research into two parts: The first part: The abstracting in the grammarians' works showing abstraction in language and terminology, then, the similar meanings. I clarified the link between  abstraction and taking the evidence off, and I revealed the word of abstraction in the works of grammarians. The second part:  The effect of abstraction to direct a speech evidence, I clarified the importance of abstraction on the speech directing . Finally, I concluded the research with a conclusion including the most important results.
