Another question has occurred to me. It is common knowledge, I assume, that Americans use the word "neat" where Brits would use the word "nice". "Neat shirt", "Hey , really neat guitar-picking" (I can only speak from personal experience, you understand. In Britain, "neat" means "tidy", "well-ordered").What I don't know, however, and would dearly love to have explained, is the exact connotation that Americans put on the word "nice".
Looking forward to elucidation.
