同义词辨析

  • 以下词都有“能,可能,可以”的意思,区别是:
  • can和may常被错用,应注意3点

    1.can表示体力或智力方面的能力。may没有这种功能。

    2.can和may都可表示请求允许做某事,前者较口语化,最常用;may用于正式文体,多含尊敬之意。

    3.can和may都可能表示可能性,前者表理论上的可能性,而后者表示现实的可能性。在这种用法中,can一般不能用来表将来的可能性,多用在否定和疑问句中表现在的可能性,而may既可表现在又可表将来的可能性。

  • 以下词都有“罐头”的意思,区别是:
  • can 为美国英语,现在英国也用。

    in 为英国英语。

can (v.1)

Old English 1st & 3rd person singular present indicative of cunnan "to know," less commonly as an auxiliary, "to have power to, to be able," (also "to have carnal knowledge"), from Proto-Germanic *kunnjanan "to be mentally able, to have learned" (source also of Old Norse kenna "to become acquainted, try," Old Frisian kanna "to recognize, admit, know," German kennen "to know," Middle Dutch kennen "to know," Gothic kannjan "to make known"), from PIE root *gno- "to know."

It holds now only the third sense of "to know," that of "to know how to do something" (as opposed to "to know as a fact" and "to be acquainted with" something or someone). Also used in the sense of may, denoting mere permission. An Old English preterite-present verb, its original past participle, couth, survived only in negation (see uncouth), but compare could. The present participle has spun off with a deflected sense as cunning.

can (n.)

generally, "a small cylindrical sheet-metal vessel used to contain liquids, preserves, etc.," Old English canne "a cup, container," from Proto-Germanic *kanna (source also of Old Saxon, Old Norse, Swedish kanna "a can, tankard, mug," also a unit of measure, Middle Dutch kanne, Dutch kan, Old High German channa, German Kanne). Probably an early borrowing from Late Latin canna "container, vessel," from Latin canna "reed," also "reed pipe, small boat;" but the sense evolution is difficult.

Modern sense of "air-tight vessel of tinned iron" is from 1867. Slang meaning "toilet" is c. 1900, said to be a shortening of piss-can; meaning "buttocks" is from c. 1910, perhaps extended from this.

can (v.2)

"to put up in cans," 1860, from can (n.1), especially "to put up in a sealed container for preservation." Sense of "to fire an employee" is from 1905. Related: Canned; canning.
