The traditional phonetic term between use and neglect

Abstract

This research paper aims at highlighting the reality of the phonetic term use   between the old and the modern, based on the following question research: Why did some of the old phonetic terms disappear and were replaced by other translated or updated terms?

 It turns out that an important number of old phonetic terms have not lost their validity in the modern lesson, as they are comprehensive and accurate enough for the required purpose and are still used. Frankly, the ancient linguists used the orality and the sight at that time, but this doesn't prevent that they were right most of the time, and the best proof is that they prayed for the birth of the phonetic lesson and they pioneered it.

I came up with a set of results, the most prominent are: Terms are the corner stone of different sciences, so they have to be tuned and standardized. Furthermore, a significant number of old phonetic terms are still adopted to this day because they are accurate and so suitable.
