The assimilation in phonology study has started with ancient Arabic scholars, but it was just inks on some books, it was unregularly incomplete, and was not independent, even it was named differently ; such as.

.

.

, diphthong, Substitution.

.

paronomasia and others, all of these names were aimed at the sound assimilative harmony, which became known as the Grammont law recently.

the law theorizes that the Articulatory system tends to save effort and time when articulating sounds ; this is because of the effect resulted from the sounds that are similar to each other, which causes these sounds to be merged or to be closed in terms of the articulation and its characteristics.

this article aims at uncovering the assimilation of voiceless sounds in ancient and modern studies, and summarizes at the end that there is a similarity between both studies in terms of the articulatory sound system function, that leans to the sound harmony when articulating two assimilative sounds, and differences in naming these studies and in studying this phonological phenomenon
