Semantic association binary roots in to different books of language metrics

Research treatments and discussions center around the semantic participation, which is intended to have several words that carry the same meaning identically or closelyto a large extent, after research and inventoryin the dictionary of language standards, we have dual roots in a book of some boo;s that carries a specific meaning, and this meaning is found in another root of a different book, the similarity or similarity of meanings is even when the buildings differ, and despite the congruence of the semantic origin-the general meaning of the roots derivatives- between these roots, even slight differences in meaning appeared that differentiate one root from another, this difference gives the word a certain characteristic that distinguishes it from others in use, such as if it is attached to a specific situation or is specific to a certain things, or if it is contained in a specific part that is not indicated by other root, even if they share the general meanings.
