As I write more, I continue to learn new tips on word usage: correct and incorrect. Here are two I often catch in critique group manuscripts as well as in published books:
1. Blonde vs. blond – A person is a blonde but hair is blond.
2. Lectern vs. podium – I find this misused all the time. A podium is a platform you stand on to speak, but a lectern is the goodie you stand behind and put your notes on.
