Hey, Aqua! Grammar questions.

[George K]

1. "He's got 30 years experience."
   or
   "He has 30 years of experience."

2. "I have a couple questions."
   or
   "I have a couple of questions."

3. "That's different to what I said,"
   or
   "That's different from what I said."

There are others I can't think of right now.

"Years of experience" is correct. Experience is like coffee; it's a mass noun, not a quantitative noun. (I think we call them countable nouns but I have some Oz terminology in my rolodex and it's hard to tell the difference sometimes.) So "years experience" is like saying "he has cup coffee."

Similar thing with "couple of questions." Saying you have "a couple questions" is like saying "I have pair shoes." That construction is actually colloquial in many areas of the country, but no, it's not grammatically correct.

"Different from/to" is a little more complicated, because that's a weird Brit thing so Phibes would be your man for how accurate "Different to" is over there. But for us, it's "different from." Our weird variant, which is not correct, strictly speaking, is "different than."
