I thought it would be interesting to find out which SPaG (spelling, punctuation, and grammar) skills you feel at least fairly proficient in, and how you came to develop those skills. Also, which ones give you the most trouble? ---- I used to have a really hard time with punctuation because it was never taught properly (full disclosure: or in an interesting manner) to me in elementary and middle school. So it was probably in 7th or 8th grade, when I had to write a paper or a story, that I started looking at the fiction books and textbooks I had to see how they handled things such as placement of commas, quotation marks, and hyphens, and when and how to use semi-colons. I also sometimes will google part of a sentence that I'm having trouble with in terms of proper punctuation and see how others have handled it. I'm more confident if the source is a scholarly paper or journal as opposed to, say, a blog or CNN.com (which is often riddled with SPaG errors). My spelling skills were developed in part because I read a lot and notice and remember how words are spelled. If I'm in doubt, I'll google the word. I'll also note any words I read for which I don't know the definition, and then try to use them in conversation and writing--improving both my vocabulary and spelling.
