Боб I fully understand what you are saying and it's true. I am just in a state of deep deep poverty at the moment (Russian lady came to England and tried to show off London to the full extent, now I'm poor haha!) I've been looking at some books and definitely will invest in one when the next loan comes in. It's just because it's so fresh to me, only started 4-5 months ago and have taken to it and I find the explanations from this website far better than many websites explanations.

I do need to get a grammar book though soon because I am flooding this forum with every thing that pops into my head haha.

And being from Nottingham (a big source of horrible horrible nonsensical slang) I would say deeply thought.. but I say deep for anything. For example; if someone said I looked ugly my response could be... ah man that was DEEP! but I just checked Wiktionary and deeply is an adverb so I guess it's possible.
