b) grammatically correct,
c) not entirely true,
d) all of the above.
The best answer is d. Yes, you need to know what you're doing when you employ the rules of grammar, but you don't have to memorize them. You just need to know where to look when you need them for reference.
I would love for this site to become a landing point for people who are stumped by the laws of the English language. I want it to be a useful resource, and the equivalent of a friendly face in a crowd. Because grammar shouldn't ever be intimidating. I hate to think of people not expressing a thought or idea in writing simply because the rules got in the way.
So I'm going to start doling out grammar lessons here on the blog, and I'll archive them elsewhere on the site for easy reference. I'll explain the rules, give examples of how they're used in everyday language, and share tips on how to remember them. I may not turn anyone into a word nerd like me, but I'm up to the challenge of making the rules a little easier to understand.
If you've ever found yourself wondering, "do I use it's or its? who or whom? lie or lay?" or something similar, stay tuned. I have the answers, and I can't wait to share them with you.
