Difference btw not able to sleep or couldnot sleep
Answers
Answer:
) I can't get any sleep
2) I can get no sleep
3) I can't get no sleep
(1) and (3) mean exactly the same thing; (1) is standard, while (3) is used only in dialects of English that have negative concord, a linguistic property in which adding a second negative to a sentence serves as an intensifier (rather than cancelling the first negative and turning the meaning positive, as occurs in standard American and British English). (3) is essentially never used in writing, or anywhere outside specific speech communities - many English speakers consider this form to sound "wrong" or "uneducated", so it's best to use (1) instead.
(2) is a grammatical sentence in standard English, but sounds strange and would be rarely used. It also has two possible meanings (it is ambiguous), depending on context. It could mean the same thing as (1); if this is your intent, use (1), as it sounds much more natural. However, it could be that in contrast to (1) which asserts the speaker's inability to sleep, (2) asserts the speaker's ability to not sleep. Consider the following hypothetical conversation
