Linguistic economy in the sounds of the Holy Qur’an (motor symmetry model)

This paper explores and deals with the phenomenon of the resemblance in utterances between the vowels of the Holy Quran.
Just like consonants pursuit resemblance using for this purpose means such as assimilation, substitution and omission, pronunciation in the Holy Quran pursuits resemblance between contrasting utterances to achieve the highest degree of harmony between these utterances.
Where there is harmony between vowels, linguistic economy is achieved. The phenomenon of resemblance usually gives way to agility, smoothness and easiness in the pronunciation of vowels and consonants together, the matter that ensures the optimum means chosen by the reciter to achieve their purposes. This phenomenon is usually accompanied by economy in muscular effort, since agility and smoothness are the pillars of linguistic economy.
The objective is by no means to expect that the reciter will always seek the easiest path, but what is expected is that the reciter will attempt to achieve some harmony of whatever degree of easiness and smoothness possible.
This paper does tackle the phenomenon of resemblance through phonetic contexts in the Holy Quran in connection with the different recital manners and applications and examples on the phenomenon of resemblance.
