Jahai language
Jahai is an aboriginal Mon–Khmer language spoken by the Jahai people living in the montane rainforests of northern Peninsular Malaysia and southernmost Thailand. It is the largest Northern Aslian language. Though spoken by only a little more than 1,000 people, Jahai does not appear to be in immediate danger of extinction due to the prevalence of Jahai parents passing on the language to their children as their mother tongue.
Jahai has a unique vocabulary for describing odors.
