For a long time to me hearth was pronounced herth, not harth. I thought it was like "earth" with an h at the beginning. It took a long time for my parents to convince me it was wrong. I still think herth sounds better.
OMG! I
still mess this one up. And I have a BA in English Communication!!! Another one I have to think about before saying is 'draught'. Until sometime in my recent 20's I was still pronouncing it 'drawt' and not 'draft'. Thank God I'm not a beer drinker - "Hi, what do you have on 'drawt'?" LOL
Years ago, my DW (after a few drinks) pronounced 'faux pas' as 'poof fah'. That error will never be forgotten because all our friends still use, in her honor, 'pooh fas' when referring to a 'faux pas'. Ah...good times.
Two of my friends and I have our own 'dictionary'. One of the friends is a tad on the flighty side and is constantly making up words, but not to make them up, KWIM? She just comes out with them and then, when I'm laughing so hard that I'm crying and can't answer her, she rethinks what she said and usually starts laughing to. This happens so often that we started writing them down. Some of my personal favorites:
*I needed to use the word maim, but I couldn't think of it at the time. I called her to see if she could help me remember it and I said, "What's that word when, like, a tiger bites someones arm off?" She answered, "Um, dearmicate?" (You know, much like decapitate, but for limbs instead.)
*She was talking to me about some shelf she had up in her house and she was talking about some objects position in reference to the shelf, "It's overneath it." I said, "Overneath?" She said, "Yes." She was already laughing.
*Again, my mind was blank and I called her (you'd think I know better by now) to help me remember what the addition at the end of a word is called (suffix). I said, "An addition to the beginning of a word is called a prefix. An addition to the end of a word is called a...." Her answer: "A postfix!"
*And the most famous, in our circle of friends, that is used all the time came from the following exchange:
ME: "What time are you going to lunch?"
HER: "Noon-thirty."
