| 词汇 | a |
| 词根词缀 | 词源： 1. a (1) indefinite article, c.1150, a variation of O.E. an (see an) in which the -n- began to disappear before consonants, a process mostly complete by mid-14c. The -n- also was retained before words beginning with a sounded -h- until c.1600; it still is retained by many writers before unaccented syllables in h- or (e)u-, but is now no longer normally spoken as such. The -n- also lingered (especially in southern England dialect) before -w- and -y- through 15c. 2. a (2) as in twice a day, etc., from O.E. an "on," in this case "on each." The sense was extended from time to measure, price, place, etc. The habit of tacking a onto a gerund (as in a-hunting we will go) died out 18c. 词根记忆： art. 一(个);每一(个);(同类事物中)任一个I work eight hours a day.我一天工作八小时. |
