inspires strong opinions. Most people, and even many authors, use rules of grammar and understanding of grammar as best practices that help enable clarity of communication.

I’ve said it many times on the site: I have something of a love affair with the English language. Where some people moan over homonyms and homophones, or grumble about synonyms and antonyms, or the fact that tenses are so erratic, to me they are features, not flaws.
