While I do have a penchant for the writing rules, my love for them is not the primary reason why I write about them. I write about them because they are a means to an end. More effective writing and better communications are found in knowing the rules.
Those two things aren’t found solely in knowing the rules; they also are found in breaking them. In order to break the rules, though, you first have to know them. They have to be dear to your heart. You then have to know why you’re breaking a rule. You have to know how to do it in a way that creates the desired effect.
It’s for that reason I write about the rules. I write about the tricky words. I write about punctuation marks. I write about tenses and types of verbs. I write about them because they are important to me and my writing, and they are important to you and yours.
