词汇	once
词根词缀	词源： c.1200, anes, from ane "one" + adverbial genitive. Replaced O.E. æne. Spelling changed as pronunciation shifted from two syllables to one after c.1300. Pronunciation change to "wuns" parallels that of one. As an emphatic, meaning "once and for all," it is attested from c.1300, but this now is regarded as a Pennsylvania German dialect formation. Meaning "in a past time" (but not necessarily just one time) is from c.1250. Once upon a time as the beginning of a story is recorded from 1595. Slang once-over "inspection" is from 1915. At once originally (c.1230) meant "simultaneously," later "in one company" (c.1300), and preserved the sense of "one" in the word; the phrase typically appeared as one word, atones; the modern meaning "immediately" is attested from 1531. 词根记忆： ad.一次,曾经conj.一(旦)…就…n.一次Nowadays the once unknown snowy hill is well-known for snowstorm.如今那座曾经不出名的多雪小山因暴风雪而出名.
