Abstract: This paper is a discussion on the consonant clusters and syllable structure found inMehri language, spoken in the south of the Arabian Peninsula, in the Republic of Yemen, by the Mahrainhabitants in the desert steppe of Yemen, and in Oman particularly in the mountains of Dhofarand in the Omani desert plateau in Sultanate of Oman. Mehri language is a Modern South Arabian language (MSALs) that descended from the Semitic languages of the Afro-Asiatic language family.
