汉：来源于拉丁语的multus,意为“many,much”。没有用来专门指具体数量的，亦可以当词根讲。前缀muiti- 相应的希腊语前缀为：poly- / pleio- 多

英：before vowels mult-, word-forming element meaning "many, many times, much," from comb. form of L. multus "much, many," from PIE *ml-to-, from root *mel- "strong, great, numerous" (cf. L. melior "better," Gk. mala "very, very much"). Many words that use it (multinational, etc.) are 20c. coinages.
