Well, I once heard that you are supposed to learn one new thing every day. Today, I simply relearned something that I already knew. I'm always right.
Take this entry for example (taken straight from The Associated Press Stylebook and Libel Manual p.146)
Over It generally refers to spatial relationships: The plane flew over the city. Over can, at times, be used with numerals: She is over 30. I paid over $200 for this suit. But, more than may be better: Their salaries went up more than $20 a week. Let your ear be your guide.
Style isn't always grammatically correct. Or, as I also learned today "grammatically schrammatically."
