Can, transitive verb [imperfect or past participle Canned; present participle or verbal noun Canning.]

To preserve by putting in sealed cans [U. S.] “Canned meats” W. D. Howells.

a general name for fruit, vegetables, meat, or fish, preserved in hermetically sealed cans.

Can, transitive or intransitive verb [The transitive use is obsolete.] [imperfect Could (#).] [OE. cunnen, cannen (1st sing. pres. I can), to know, know how, be able, AS. cunnan, 1st sing. pres. ic cann or can, pl. cunnon, 1st sing. imp. cūðe (for cunðe); p. p. cūð (for cunð); akin to OS. Kunnan, D. Kunnen, OHG. chunnan, G. können, Icel. kunna, Goth. Kunnan, and E. ken to know. The present tense I can (AS. ic cann) was originally a preterit, meaning I have known or Learned, and hence I know, know how. √45. See Ken, Know; cf. Con, Cunning, Uncouth.]

1. To know; to understand. [Obs.]

I can rimes of Robin Hood. Piers Plowman.

I can no Latin, quod she. Piers Plowman.

Let the priest in surplice white,
That defunctive music can. Shak.

2. To be able to do; to have power or influence. [Obs.]

The will of Him who all things can. Milton.

For what, alas, can these my single arms? Shak.

Mæcænas and Agrippa, who can most with Cæsar. Beau. & Fl.

3. To be able; – followed by an infinitive without to; as, I can go, but do not wish to. Syn. – Can but, Can not but. It is an error to use the former of these phrases where the sens requires the latter. If we say, “I can but perish if I go,” “But” means only, and denotes that this is all or the worst that can happen. When the apostle Peter said. “We can not but speak of the things which we have seen and heard.” he referred to a moral constraint or necessety which rested upon him and his associates; and the meaning was, We cannot help speaking, We cannot refrain from speaking. This idea of a moral necessity or constraint is of frequent occurrence, and is also expressed in the phrase, “I can not help it.” Thus we say. “I can not but hope,” “I can not but believe,” “I can not but think,” “I can not but remark,” etc., in cases in which it would be an error to use the phrase can but.
