It is you who are/is ...
was talking with someone via Facebook. I thought she was wrong, and she wrote back to me: “No, Donna, it is you who are wrong”. Had she left out the word “who” then I believe “are” would be correct, but since she included the word “who” then it changes to singular “you” which would require the word “is”. I believe it shoud read “No, Donna, it is you who is wrong”. Please help me on this grammatical issue.

The pronoun "you" always takes a plural verb, even when the object is singular, as in your example.
Leave out the "who" and you'd have either "you are wrong" or "you is wrong". "Who," in your example, modifies "you." It's neither the subject ("you" is the subject--and there's an example of an exception to the rule I stated initially, but that's because what I'm really saying is "The word {fill in the blank} is the subject") nor the object of the verb "to be."
Hope this helps!

Donna, it's you who are wrong.  The word "who" is not inherently third-person singular; it takes its person and number from the noun it's referring to.  It can be singular or plural, and first person, third person, or (as in your case) second person.

Insist on vs Insist in
Are both of the two options possible? if not, which is correct?
Give me examples (senteces) if possible.
Thanks in advance

Hi, I would always use insist on

eg. He insisted on paying
eg. I always insist on the best
I don't think that insist in is correct, not in British English anyway.
Hope that helps.

How about "To insist in the face of adversity"??

Sorry, I think I was wrong, exist in, is only possible in the example I gave, to use" in" you have to use "persist in"
So sorry but it has to be insist on

I have two questions on the verb 'dare'. Which one is correct:'I wouldn't dare to ask.' or 'Iwouldn't dare ask.' or 'I wouldn't dare asking.'? Why? Which one is correct: 'He dare do it.' or 'He dare to do it.' or 'He dare doing it.' or 'He dares do it.' or 'He dares to do it.' or 'He dares doing it.'? Why? Thank you very much for your help.
The verbs need and dare sometimes function as modal (auxiliary) verbs and sometimes as regular (lexical -- which would use an infinitive) verbs. Both verbs are called "marginal modal auxiliaries." In the modal construction, we would write: "He dare not go now." "Dare he go now?" "No solder dare disobey." "No one dare predict." In the lexical construction, you could write: "He dares to go now." "He doesn't dare to go now." "Does he dare to go now?"

dare  (dâr)
v.dared, dar·ing, dares
v.tr.1. To have the courage required for: The gymnast dared a breathtakingly difficult move.
2. To challenge (someone) to do something requiring boldness: They dared me to dive off the high board.
3. To confront or oppose boldly. See Synonyms at defy.

v.intr. To be courageous or bold enough to do or try something: Go ahead and dive if you dare.

v.aux. To be courageous or bold enough to: I dare not say. How dare she go?

n. An act of daring; a challenge.

Usage Note: Depending on its sense, the verb dare sometimes behaves like an auxiliary verb (such as can or may) and sometimes like a main verb (such as want or try). When used as an auxiliary verb, dare does not change to agree with its subject: Let him say that if he dare. It also does not combine with do in questions, negations, or certain other constructions: Dare we tell her the truth? I dare not mention their names. Finally, it does not take to before the verb that follows it: If you dare breathe a word about it, I'll never speak to you again. When used as a main verb, dare does agree with its subject (If he dares to show up at her house I'll be surprised), and it does combine with do (Did anyone dare to admit it?). It may optionally take to before the verb following it: No one dares (or dares to) speak freely about the political situation. The auxiliary forms differ subtly in meaning from the main verb forms in that they emphasize the attitude or involvement of the speaker while the main verb forms present a more objective situation. Thus How dare you operate this machinery without proper training? expresses indignation at the action, whereas How do you dare to operate this machinery without proper training? is a genuine request for information. When dare is used as a transitive verb meaning "challenge," only main verb forms are possible and to is required: Anyone who dares him to attempt it will be sorry.
