Kolln and Sentence patterns
Chapter two was full of new information for me. I do not remember learning to diagram sentences in elementary school or high school. I liked that Kolln explained what a noun phrase, a noun, a verb phrase and a verb was. The whole diagraming thing brings a new light to the English language for me: it doesn't matter if you know all the rules, what matters is if you know all the exceptions to and modifications of the rules.
How has your grammar changed during your college years? Which definition (from Kolln) do you associate as your definition of grammar?
