前缀 over-

汉：来源于盎格鲁-撒克逊语，意为“above,across,beyond,excessive”
英：word-forming element meaning "above; highest; across; too much; above normal; outer," from O.E. ofer (see over). Over and its Germanic relations were widely used as prefixes, and sometimes could be used with negative force, though this is rare in Modern English. Cf. Goth. ufarmunnon "to forget," ufar-swaran "to swear falsely;" O.E. ofercræft "fraud."
