@glwood, I’m so glad you bring this up. It’s a pet peeve of mine too. I’m a writer and public speaker. I appreciate this one you mentioned and added a few of my own
Lose, not loose or vice versa, usually the latter in place of the former.
A lot, not alot, which is not a word
In case, not incase.
Grate, not grade, when you are preparing the cheese for tacos
Here is one that is almost always mispronounced and annoys me.
Mischievous, pronounced by most people miss-cheevey-us. Makes them sound like an idiot.
However, I will remark, that while I always seek to uphold the rules of English grammar (and two other languages), if you listen to linguistic experts, like Noam Chomsky, they will tell you that the reason English is so hard to learn is because the rules are wrong. He cites several rules made up by one guy over here hundreds of years ago and a monk over there hundreds of years ago. The rules are often so counterintuitive that you just have to beat them into your brain to be right (or are you wrong?).
Tomato, tomato. Is it "real-a-tor" or "real-ter?"
