Nominative (or subjective) Case Pronouns are used as subjects and predicate nominatives. The nominative case pronouns are I, he, she, it, we, they, and who... For the pronoun to be a predicate nominative, the verb must be LINKING. The verb in your example is, er, "is". In your sentence you have the word "who" which is related to the main subject "it", therefore you must use "decide".
It is clear now, thank you
. If so, why 9 out of 10 natives say "it is you who decides"? Can I compare this language situation to "It is I" and "It is me" where "It is me"predominates although "It is I" is perfectly correct?
Or perhaps to froms "I am good" and "I am well" where "I am good" is used overhemingly by native speakers as an answer to "how are you"
The most difficult thing in learnig English is the fact that English is changing so quickly that the connent of grammar books becomes simply irrelevant. I have no problem with this as it indicates that the language is alive and active. It makes English interesting but what I am supposed to say to my students?
Learn what grammar says but take into account that it might be irrelevant or even invalid?:shock:
Objective Case Pronouns are used as direct objects, indirect objects, and objects of the preposition. These objective case pronouns are you, me, him, her, you, us, them, and whom...
Is that better?
Yes, that's better now. Put it into a question: "who decides?"
