The word "China" has been used in English since the 16th century; however, it was not a word used by the Chinese themselves during this period. Its origin has been traced through Portuguese, Malay, and Persian back to the Sanskrit word Chīna, used in ancient India.[19] "China" appears in Richard Eden's 1555 translation[l] of the 1516 journal of the Portuguese explorer Duarte Barbosa.[m][19] Barbosa's usage was derived from Persian Chīn (چین), which was in turn derived from Sanskrit Cīna (चीन).[24] Cīna was first used in early Hindu scripture, including the Mahābhārata (5th century BCE) and the Laws of Manu (2nd century BCE).[25] In 1655, Martino Martini suggested that the word China is derived ultimately from the name of the Qin dynasty (221–206 BCE).[26][25] Although usage in Indian sources precedes this dynasty, this derivation is still given in various sources.[27] The origin of the Sanskrit word is a matter of debate, according to the Oxford English Dictionary.[19] Alternative suggestions include the names for Yelang and the Jing or Chu state.[25][28] The official name of the modern state is the "People's Republic of China" (simplified Chinese: 中华人民共和国; traditional Chinese: 中華人民共和國; pinyin: Zhōnghuá Rénmín Gònghéguó). The shorter form is "China" Zhōngguó (中国; 中國) from zhōng ("central") and guó ("state"),[n] a term which developed under the Western Zhou dynasty in reference to its royal demesne.[o] It was then applied to the area around Luoyi (present-day Luoyang) during the Eastern Zhou and then to China's Central Plain before being used as an occasional synonym for the state under the Qing.[30] It was often used as a cultural concept to distinguish the Huaxia people from perceived "barbarians".[30] The name Zhongguo is also translated as "Middle Kingdom" in English.[32] China (PRC) is sometimes referred to as the Mainland when distinguishing the ROC from the PRC.[33][34][35][36]
