There is a word that I don't think of nor use very often. When I use the word in conversation, I have a doubt about the correct enunciation but I don't worry about. I just let it rip.
The word is "SCARCE." When it comes out of my mouth, I usually pronounce it as SCAR-ce. When I do that, people freak out. What did you say? That is not even a word? It has happened a few times and I am amazed that people find it so disturbing.
My brother-in-law even gave me a grammar lesson on silent-E's and gates and all that. He told me it should always be pronounced SCARE-ce. But there are many words that break that long-vowel/gate rule; like have, give and most of all FARCE.
I'm just going to think of it as one of those "you say tomato, I say tornado" things.
