Wlcome to the forum, Van Veen.
Some of the examples here suggest that a tin-cup exercise would involve requesting money in some way.Quite.
As a snide aside - why does this website use the word "forums" instead of the correct Latin "fora?" Presumably it's because the site is about the English language (as opposed to Latin) and common usage has rendered "forums" acceptable.No. Most of us here give of opinions on how the language is used, not how some self-appointed experts think it should be used.However, when one is discussing proper usage one is (I assume) applying a prescriptivist approach.I don't quite understand your point/question.Best to know the accepted rules from which we may consciously diverge?
