Also (as @Kris points out in a comment), cannot might be used when you need to carefully distinguish it from can't in speech.Mon, 06 Apr 2026 18:34:00 GMThttps://english.stackexchange.com/questions/565474/what-is-the-difference-between-can-not-cannot-and-cantThe phrase "can not" may mean "cannot" or "can't," but it also may mean "able not to," which is much different than "not able to" as it conveys the ability to not do something rather than the inability to do it.Tue, 14 Apr 2026 20:48:00 GMThttps://english.stackexchange.com/questions/612777/the-usage-of-can-not-vs-cannot-in-mathematicsSo here it’s about minimizing ambiguity: can not permits two interpretations, while cannot permits only one. Such care is critical in the language of mathematics. As another example, West would tell you that in mathematical discourse, both “x is a minimum” and “x is a minimal” are valid utterances, but they mean different things.Sun, 12 Apr 2026 19:53:00 GMThttps://english.stackexchange.com/questions/4510/why-is-cannot-spelled-as-one-wordWhy is “cannot” spelled as one word whereas other similar constructions such as “do not,” “will not,” “shall not,” “may not” and “must not” are spelled as two words (unless they are contracted as “...Thu, 16 Apr 2026 15:37:00 GMThttps://english.stackexchange.com/questions/204006/cannot-vs-can-notSo, "cannot" means something (denoted S) is impossible, while "can not" means the inverse of that something (denoted !S) is possible. These two statements do not imply each other. Of course, the second statement could be rendered much more clearly as "The variable can be not initialized," by moving the "not" next to the word being negated.Sat, 11 Apr 2026 17:45:00 GMThttps://english.stackexchange.com/questions/50251/is-it-incorrect-to-say-why-cannotCannot is the only negative form that contains not rather than -n't. Theoretically, since it is a single word, you can say why cannot you... without a problem. My theory is that modern English speakers don't want to put cannot before the subject because it contains not and sounds like can not.Mon, 13 Apr 2026 01:15:00 GMThttps://english.stackexchange.com/questions/528646/is-cannot-be-overstated-sloppy-writing-1 Saying that something "cannot be overstated" is exaggeration and clearly never true, because anything can be overstated. (You just keep repeating that thing to the exclusion of everything else: now it is overstated.) So is using this phrase sloppy writing, or is it a well-understood phase that no longer means what it appears to mean?Sun, 12 Apr 2026 14:09:00 GMThttps://english.stackexchange.com/questions/18685/you-cannot-eat-your-cake-and-have-it-or-have-your-cake-and-eat-itThe irony of the idiom is that one would expect to be able to eat the cake that he or she owned. In that case, possession of the cake would logically come before usage of the cake: You cannot have your cake and eat it, too. Some other interesting observations: Paul Brians, Professor of English at Washington State University, points out that perhaps a more logical or easier to understand ...Mon, 13 Apr 2026 06:44:00 GMThttps://english.stackexchange.com/questions/597311/what-do-you-call-a-person-who-cannot-learn-to-use-computersYou could (in my opinion, unfairly) describe yourself as: Superannuated Retired because of age or infirmity Too old for use, work, service, or a position Antiquated or obsolete Collins Dictionary: Superannuated While it doesn't specifically address computers or an inability to learn, it does capture the general feeling of "being unable to adapt to modern technology".
