Being an ex-writng major, I pride myself in my ability to (most of the time) correctly use adjective and adverbs. However, during most of my education process, although I learned the rules, I didn't know these rules were, it was usually "just because." I was one of those things where didn't really matter if you knew why you were right, as long as you were right. With that being said, I don't believe I was ever officially taught the basic rules for using adjective, I just trusted my sense of "does it
sound right?" I know that the Purdue OWL website has always been available to me, so if I really wanted to, I could have learned the official rules on my own, but I never did. After reading "The Basic Rules: Adjectives" article, I learned the technical terms for many concepts that I already knew. For example, it seems pretty obvious, but I didn't know the terms "countable nouns" and "uncountable nouns" was a technical term, for me it was always just "singular" or "plural." In addition to this, I had never sat down and read the rules for the use of individual adjectives. Obviously I knew that a sentence like "he had many moneys" was not grammatical, but I never would have been able to tell you the reasoning behind that is that "money" is an uncountable noun and the adjective "many" can only be used with countable nouns.
