If you didn't add so many unnecessary letters in your words, maybe we wouldn't try to hack the language.
Anyways a word that a JW will almost ALWAYS mispronounce.
She'ol. It's supposed to be pronounced "She -OL" (Sounds like She BOWL)
Not SHE-awl or "SHE ol'. I talked to a rabbi about the concept of Sheol and he gave me a funny look. Needless to say, I told him who taught me how to pronounce the word and he shook his head in pity.
