前綴 auto-

漢：來源于希臘語，意為"self"。在元音字母和輔音字母h前，字母o脫落，變?yōu)閍ut,還有變化型為auth-。近來，源于盎格魯-撒克遜語的self有比auto更常用的傾向。
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-.
