Because the word "at" is a preposition and it is considered grammatically incorrect to end a sentence with a preposition.
No. It is wrong because the "at" is unnecessary. An English sentence may properly end with preposition, for example: Forcing English to comply with Latin grammatical rules is a school-marm trick that no natural speaker puts up with.
No.
Either "Where is he, today?" if you are asking about his geographic location,
or "What is he doing today?" if you are asking about his activities,
or "How is he feeling today?" if you are asking about his mental state.
Where he's at is a non-standard form of speech.
Not in Standard English, and certainly not in reference to a thing's location The construction "where it is at" may be used by well-spoken hipsters, but only in reference to a thing's nature, purpose or condition. Thus we may say that smoking tobacco is not where it's at, meaning it has no cool, no cachet. Bob Dylan's line "He really wasn't where it's at" means he was not the right one.
Where is it? is the correct form. Omit at.
No, it is not. The correct sentence is "Where are you?"
You should say for your convenience it is *gramatically correct-*just means correct
It is not grammatically correct to say ' you go to home'. Instead you should leave out the word to, and say 'you, go home'.
Neither are correct in my view. In Australia, we say βmore tannedβ.
If you want to be gramatically correct, you should say "ten to one" since "till" is slang but if you are just talking or posting something informal, "ten till one" is fine. I think.
be rest assured
Yes it is correct to say "Have a wonderful Holiday."
Yes it is.
You should say for your convenience it is *gramatically correct-*just means correct
Yes.
Yes, there is a verb and and a noun and they are in the same tense therefore it is gramatically correct.
That's not even a complete sentence. The words TO, SAT, THIS, PEOPLE and IS can not be combined in any way to make a grammatically correct sentence. ------------------------------------------------------------------------------------------------------------- Assuming the question should be Is it gramatically correct to say, "This people is..."? then it is not correct. One should say, "These people are...".
No, it is not grammatically correct. The correct form would be "Why would you worry instead of being happy?"
I don't see why not although beginning a sentence with 'or' is unusual.
No. It would be better to just say those or these.
Yes. "She has no idea that you are even here." is a correctly formed, gramatically correct sentence.
No. You would normally say something like higher up.
No. I would say: "You and her will begin to ship the product".
