Thanks for straightening me out on this, Dupre. I was wrong thinking that an appositive wasn't an adjectival. (Don't know what got into me!
) You're sure right, English is a funny language. These rules about using or not using a possessive form with a gerund are amazing. I think most of us get by with sounds right or doesn't sound. Guess that's intuitive, but I never knew some of these rules and I couldn't find them either!
How is it that you're researching this, do you mind me asking?
