Not a single friend came to the party makes more sense? Or maybe 'not one friend came to the party. To me it sounds like it could possibly be grammaticallty correct, but you never know.
'Did she came...' is incorrect. 'Did she come...' is correct.
Yes. That's correct.
Yes, the phrase "I came home at about one o'clock" is grammatically correct. It follows a subject-verb-object structure and conveys a clear message about the time of arrival.
I came to your office several times and did not see (s) you._______Better:I came to your office but could not find you.
"The men came today to lay the carpet in the living room" is grammatically correct. One could use less words though - "The men came today to lay the living room carpet".
The correct grammar for this sentence is: When did your friend come?
The 2nd one
No this is incorrect grammar. To make the sentence grammatically correct you should say: One of my cousins came yesterday.
The phrase "she came ot my home yesterday" is correct... although a little formal. If you are talking to friends, you would be more likely to hear "she came over" rather than "she came to my home." But if you are writing a paper for class, the form you already have is probably best.
Either, depending on the usage. Both of the following are correct: Who came to the party? If you didn't come, then who did come?
You can't answer this without the rest of the sentence. "He and his friend came to see me; I asked him and his friend to sit down." is an example of correct usage.
No, that isn't grammatically correct.You should say "Why didn't you come to my home?"The helper verb "to do" is conjugated (did, did not) but the verb (come) is not.
