So the fact I understand, and attempted to explain to you, the difference between a noun the Premier League and an adjective the premier league makes me stupid. To clarify are you arguing that:
a) The Premier League is not a noun
b) That you actually just meant the premier league and made a mistake
c) That everyone else in the world is incorrect as regards what a noun is, what an adjective is and how their implementation affects the meaning of sentences
You must simply be wumming, no-one can legitimately argue what you're arguing. Just go mental calling everyone around you thick and quoting things of the internet which you don't understand if you wish - if it makes you feel better then go for it but it doesn't make you any less incorrect. Shame they didn't teach you better grammar in a grammar school really, I'd hate to see what your mathematics was like.
