Hobson-Jobson — L
(1903)
“ LAOS, n.p. A name applied by the Portuguese to the civilised people who occupied the inland frontier of Burma and Siam, between those countries on the one hand and China and Tongking on the other; a people called by the Burmese Shans, a name which we have in recent years adopted. They are of the same race of Thai to which the Siamese belong, and which extends with singular identity of manners and language, though broken into many separate communities, from Assam to the Malay Peninsula. ”
