iso-
IPA: PHONETIC RESPELLING:
在元音前常为 is- ，作为构词元素意为“相等，相似，相同;等距的，等角的”。源自希腊语 isos “等于，相同，；平分；公平，（对人）公正的；（地面）水平的”，as in isometor "like one's mother." （此段翻译有待商榷） 。在英语中仅适用于希腊语单词;拉丁语中的同义词是 equi- (参见equi-)。
before vowels often is-, word-forming element meaning "equal, similar, identical; isometric," from Greek isos "equal to, the same as; equally divided; fair, impartial (of persons); even, level (of ground)," as in isometor "like one's mother." In English used properly only with words of Greek origin; the Latin equivalent is equi- (see equi-).
