Editing Sino-Tibetan languages (section)

===Early work===
During the 18th century, several scholars noticed parallels between Tibetan and Burmese, both languages with extensive literary traditions. Early in the following century, [[Brian Houghton Hodgson]] and others noted that many non-literary languages of the highlands of northeast India and Southeast Asia were also related to these. The name "Tibeto–Burman" was first applied to this group in 1856 by [[James Richardson Logan]], who added [[Karen languages|Karen]] in 1858.{{sfnp|Logan|1856|p=31}}{{sfnp|Logan|1858}} The third volume of the ''[[Linguistic Survey of India]]'', edited by [[Sten Konow]], was devoted to the Tibeto–Burman languages of [[British India]].{{sfnp|Hale|1982|p=4}}

Studies of the "Indo–Chinese" languages of Southeast Asia from the mid-19th century by Logan and others revealed that they comprised four families: Tibeto–Burman, [[Tai languages|Tai]], [[Mon–Khmer languages|Mon–Khmer]] and [[Malayo-Polynesian languages|Malayo–Polynesian]]. [[Julius Klaproth]] had noted in 1823 that Burmese, Tibetan, and Chinese all shared common basic [[vocabulary]] but that [[Thai language|Thai]], [[Mon language|Mon]], and [[Vietnamese language|Vietnamese]] were quite different.{{sfnp|van Driem|2001|p=334}}{{sfnp|Klaproth|1823|pp=346, 363–365}} [[Ernst Kuhn]] envisaged a group with two branches, Chinese–Siamese and Tibeto–Burman.{{efn|{{harvp|Kuhn|1889|p=189}}: "wir das Tibetisch-Barmanische einerseits, das Chinesisch-Siamesische anderseits als deutlich geschiedene und doch wieder verwandte Gruppen einer einheitlichen Sprachfamilie anzuerkennen haben." (also quoted in {{harvp|van Driem|2001|p=264}}.)}} [[August Conrady]] called this group Indo–Chinese in his influential 1896 classification, though he had doubts about Karen. Conrady's terminology was widely used, but there was uncertainty regarding his exclusion of Vietnamese. [[Franz Nikolaus Finck]] in 1909 placed Karen as a third branch of Chinese–Siamese.{{sfnp|van Driem|2001|p=344}}{{sfnp|Finck|1909|p=57}}

[[Jean Przyluski]] introduced the French term ''sino–tibétain'' as the title of his chapter on the group in [[Antoine Meillet|Meillet]] and [[Marcel Cohen|Cohen]]'s ''Les langues du monde'' in 1924.{{sfnp|Przyluski|1924|p=361}}{{sfnp|Sapir|1925|p=373}} He divided them into three groups: Tibeto–Burman, Chinese and Tai,{{sfnp|Przyluski|1924|p=361}} and was uncertain about the affinity of Karen and [[Hmong–Mien]].{{sfnp|Przyluski|1924|p=380}} The English translation "Sino–Tibetan" first appeared in a short note by Przyluski and [[Gordon Luce|Luce]] in 1931.{{sfnp|Przyluski|Luce|1931}}
