ARABIC LANGUAGE SONOROUS SOUNDS IN THE ANCIENT ARABIC LESSON OF SOUNDS: DESCRIPTIVE AND ANALYTICAL STUDY

Among what some oriental researchers had decided, and has been followed by many of modern Arab researchers, is that the ancient arabic linguistics didn't pay attention to sonorous sounds in Arabic language so well as their consideration to the mute sounds. Their point of view is that these sounds got only superficial mentions, therfore, they didn't arrive to define the nature of these letters pretending that ancient phonologique scientists were considering them casual sounds, a part of mute sounds, in addition their effectiveness to the script more than their effectiveness to the aural. Although, if we get back to the patrimonial phonetic resources and read our ancient Arab scientists achievement, we find the opposite. What they arrived to in their researches in the description of sonorous sounds in its physiological and physical parts, or in its functional and syntactic parts, is not far from that proved by modern researchers of phonetics. Thus, this research will, trough description and analysis, work on the study of sonorous sounds in Arabic language by our ancient scientists. It will also see in the importance of their sonorous achievement.
