Sorry I don't get the question.
The phrase "is all" can be correct grammar in certain contexts, such as when emphasizing that something is entirely or completely the case. For example, "The cake is all gone" or "Her argument is all wrong."
Yes, "To those who are Irish" is correct grammar. It is a prepositional phrase that correctly identifies a specific group of people.
If you are referring to this sentence, no, it does not resemble a correct phrase AT ALL.
No, the phrase "of which we are all" is not grammatically correct. It would be better to say "of which we all are" or simply "which we all are."
No, it is not correct. The correct way to phrase it would be "Thank you to all of you."
Yes, the grammar in the sentence is correct. It conveys the idea that words are the only thing remaining in a situation.
The correct phrase is "all of a sudden". Bad grammar is often spread because the phrase is misheard, and "all of a sudden" sounds very similar to "all the sudden" or "all of the sudden" when a person says it quickly.
Your question is grammatically and idiomatically incorrect in many ways. First of all "grammar", the way you are using it, cannot take the indefinate article "a". It is idiomatic to say "Is [quote sentence here] correct grammar?" So it would appear that the phrase/ sentence you are asking about is "It does she clears your doubt." There are too many verbs and pronouns in this. Is the subject "it" or "she"? Is the verb "does" or "clears"? Either way, these are not verbs that can be used coherently with the object "doubt"--that is not a grammar problem but a usage problem. As a result it is impossible to get any meaning from this heap of words.
All is well
If you are referring to this sentence, no, it does not resemble a correct phrase AT ALL.
It depends on the structure of the entire sentence. For example, "Bill, Bob, and I are going to the grocery store" is correct grammar in that sentence, but "Sandra is going to meet Bill, Bob, and me" is also grammatically correct because of the structure of its sentence. It really all depends upon the context in which the phrase "Bill, Bob, and I" are being put into. == ==
It certainly can be correct. As with all grammar it depends on how it is used
I think its all of which had
Either form is acceptable.
Attendance is required for all employees.
The sentence All credits go to him, is not correct grammar, and it should be corrected to All credit goes to him.
First of all, it should be: Is Spelman an all-girls' college?The answer? Yes. Yes it is.I'm also assuming that understanding and using correct grammar is one requirement of acceptance.
It actually would be phrased as "who all had."
