I'm in a bit of a quandary right now as to what kind of grammar to use around Amy when it comes to subject vs. object forms of pronouns.
The thing is, I was taught to use the subject form ("I, he, she") in certain constructions, but it seems to me that the object form ("me, him, her") is more natural to a large number of native English speakers.
The subject form is more correct according to conservative, prescriptive grammar; it also matches with what German (which inflects more strongly than English) does. But I wonder whether I should use this form or whether it's dated and unnatural.
The classic example is comparison statements. Does one say "He is bigger than me but she is exactly as big as me" or "He is bigger than I but she is exactly as big as I"? (There is, of course, also "He is bigger than I am but she is exactly as big as I am", where I think everyone uses the subject form of the pronouns, but that seems rather stilted to me, too, as the default form.)
Another example: Amy showed me a picture she had drawn in kindergarten and explained to me who the people on it were: "This is Anne and that am I and that is Nea". Fine in German ("das bin ich") but not only is the verb wrong for English (I think), the pronoun form is also questionable. I think it should be "...and that's ___" (with "is" rather than "are") but I'm not sure whether to say "and that's me" or "and that is I".
And a final, also classic example: responses such as "Who wants some cake? — Me!" or "Who spilt the orange juice? — Not me!", where conservative grammar would have "I" in each case (and German would have "ich").
What do you think? "I" or "me" in that sort of sentence?
And because I like polls: what is the most natural/spontaneous form you would use in the following constructions?
Tom is bigger than ___
Paul isn't as smart as ____
Look at this picture! This is Joe and this _______ and this is Paul.
Who's that on the picture? — ___________
Who wants some cake?
Who broke the window?
And the $64000 question: what form should I use when talking English to Amy?
