influence of sounds on some of them are; assimilation, dissimilation, metathesis. The question "Are there similarities
in sound phenomena between Tamil and Arabic languages which are from two different language families" is the
research problem. Thus, this research aims to identify the similarities and differences in sound phenomena among
them. This research uses qualitative methodology under the descriptive analysis to find out the similarities and
differences among them. Secondary data were collected from books, research and previous studies. This research
concludes that partial and progressive assimilation in Arabic are used in Tamil under the name "waru ozhi tirifu" as
well as other types of assimilation in Arabic such as complete, regressive, contact, distant assimilation are used in
Tamil with different names. The assimilation is reflected in the vowels and consonants of these two languages. When
comparing the dissimilation in Arabic and Tamil, this term in both languages indicates one thing. This research finds
that these two types are used in the Arabic and Tamil languages. Although these two languages belong to a different
language family.
