High Quality Content by WIKIPEDIA articles! Pattani Malay, often referred to in Thailand as Yawi, is a dialect of the Malay language spoken in the southernmost provinces of Thailand along the border with Malaysia. IT is the primary spoken language of the Thai Malay ethnic group, but is also used as a linga franca by ethnic Thai in rural areas, Muslim and non-Muslim, and the samsam, a mostly Thai-speaking population of mixed Malay and Thai ancestry. PAttani Malay is a highly divergent dialect of Malay, influenced by Thai and isolated from the rest of the Malay world by high mountains. SEveral varieties exist, but they are mutually comprehensible. IT is almost identical to the Kelantanese Malay spoken just across the border; there has not been any detailed study to determine if they are in fact still the same language or have diverged. BOth Kelantanese and Pattani dialects are distinct enough that radio broadcasts in Standard Malay can only be understood with difficulty.
