1. If I'm is a contraction for I am, why does it sound wrong to say:
I think, therefore I'm.
2. If you've is a contraction for you have, why does it sound wrong to say:
Give me all the money you've.
3. If he'd is a contraction for he would, why does it sound wrong to say:
He'd, but I wouldn't.
4. Why does it sound acceptable to me (West Coast American English speaker) to say:
There's more carrots in the refrigerator.
even though the uncontracted form is clearly ungrammatical:
There is more carrots in the refrigerator.
Obviously, this should be There are more carrots . . . But there're is a very awkward contraction. So there's sounds better even though it is wrong?
