Grammar Girl (a.k.a. Mignon Fogarty) has put together a nice list of what she considers the top 10 grammar myths. I think she’s spot on! (Well, except for irregardless as a bona fide word. Yikes! How can it be so???)
Her list transports me back to sixth grade, when Sister Grace Agnes lorded over us with her hard-and-fast English-language rules – rules I break almost daily. Ha!
10. A run-on sentence is a really long sentence.
9. You shouldn’t start a sentence with the word “however.”
8. Irregardless is not a word.
7. There is only one way to write the possessive form of a word that ends in s.
6. Passive voice is always wrong.
5. I.e. and e.g. mean the same thing.
4. You use a before words that start with consonants and an before words that start with vowels.
3. It’s incorrect to answer the question “How are you?” with the statement “I’m good.”
2. You shouldn’t split infinitives.
1. You shouldn’t end a sentence with a preposition.
