Description

Gwoyeu Romatzyh is a system for writing Standard Chinese using the Latin alphabet. It was primarily conceived by Yuen Ren Chao (1892–1982), who led a group of linguists on the National Languages Committee in refining the system between 1925 and 1926. In September 1928, it was adopted by the Republic of China as the national romanization system for Standard Chinese. GR indicates the four tones of Standard Chinese by varying the spelling of syllables, a method originally proposed by team member Lin Yutang (1895–1976). Distinct sets of spellings are assigned to syllables in GR according to particular rules. This differs from approaches used by other systems to denote tones, like the numerals used by the earlier Wade–Giles system, or the diacritics used by the later Hanyu Pinyin system.
