Phonetic Variance in Some Pronunciations in the Arabic Language and Its Dialects

اتهاجلهو ةيبرعلا ةغللا ظافلأ ضعب في ةيتوصلا تايريغتلا

This research aims to cover assimilation which represents a fundamental phonetic phenomenon in the Arabic language such that linguistic sounds influence one another when they are uttered and therefore change the pronunciation and characteristics of certain sounds. Assimilation may occur beforehand when the preceding sound influences the following sound, or it may occur afterwards if the following sound affects the previous one. Dissimilation is the term used to describe the opposite of assimilation, for if assimilation means the combination of two sounds that have similar characteristics or are closely related when pronounced, then dissimilation means the distancing of two identical sounds in certain words such that one of them transforms into another sound, usually among the long or medium vowel sounds. Arabic scholars have used the word(نولمري) to classify this. This research therefore also aims to study the rules of ease and facilitation. As language develops it tends towards ease and facilitation, and attempts to omit difficult sounds and replace them with others that do not require great muscular effort. Among the forms of this rule in the Arabic language and dialects include: facilitating the Hamza, omitting dental sounds( ءاظلاو لاذلاو ءاثلا ), and deflecting vocalizations like placing a Kasrah on present tense affixes as well as the definite article Alif and Lam, and leaving out the pronunciation of compound sounds (aw -ay) and replacing them with long or short deflected vowels(e – ē/ o –ō).
