前缀 auto-

词缀前缀

汉：来源于希腊语，意为"self"。在元音字母和辅音字母h前，字母o脱落，变为aut,还有变化型为auth-。近来，源于盎格鲁-撒克逊语的self有比auto更常用的倾向。
英：word-forming element meaning "self, one's own, by oneself," from Greek auto- "self, one's own," combining form of autos "self, same," of unknown origin. Before a vowel, aut-; before an aspirate, auth-. In Greek also used as a prefix to proper names, e.g. automelinna "Melinna herself." The opposite prefix would be allo-.
