can, may, shall, will (see usage note at the current entry)(see usage note at shall)(see synonym study at will).


Can1 and may1 are frequently but not always interchangeable in senses indicating possibility: A power failure can (or may) occur at any time. Despite the insistence by some, that can means only “to be able” and may means “to be permitted,” both are regularly used in seeking or granting permission: Can (or May) I borrow your tape recorder? You can (or may) use it tomorrow. Sentences using can occur chiefly in spoken English. May in this sense occurs more frequently in formal contexts: May I address the court, Your Honor? In negative constructions, can't or cannot is more common than may not: You can't have it today. I need it myself. The contraction mayn't is rare.
Can but and cannot but are formal and now somewhat old-fashioned expressions suggesting that there is no possible alternative to doing something. Can but is equivalent to can only: We can but do our best. Cannot but is the equivalent of cannot help but: We cannot but protest against these injustices. See also cannot, help.

Word Origin & History

can
O.E. 1st & 3rd pers. sing. pres. indic. of cunnan "know, have power to, be able," (also "to have carnal knowledge"), from P.Gmc. *kunnan "to be mentally able, to have learned" (cf. O.N. kenna "to know, make known," O.Fris. kanna "to recognize, admit," Ger. kennen "to know," Goth. kannjan "to make known"),
from PIE base *gno- (see know). Absorbing the third sense of "to know," that of "to know how to do something" (in addition to "to know as a fact" and "to be acquainted with" something or someone). An O.E. preterite-present verb, its original p.p., couth, survives only in its negation (see uncouth), but cf. could. The prp. has spun off as cunning.

can
O.E. canne "a cup, container," from P.Gmc. *kanna (cf. O.S., O.N., Swed. kanna, M.Du. kanne, Du. kan, O.H.G. channa, Ger. Kanne), probably an early borrowing from L.L. canna "container, vessel," from L. canna "reed," also "reed pipe, small boat;" but the sense evolution is difficult. Modern "air-tight
vessel of tinned iron" is from 1867 (can-opener is from 1877). Slang meaning "toilet" is c.1900, said to be a shortening of piss-can. Meaning "buttocks" is from c.1910. The verb meaning "to put up in cans" is attested from 1871; that of "to fire an employee" is from 1905. Related: Canning. Canned "pre-recorded" first attested 1904.
