Here are some of my favorite words:
RE words: revelation, reactionary, revolution
*These words sound strong and round.
Words whose synonyms I detest: flatulent, skivvies
*I loathe the word fart. And dislike the word underwear. I'm also not crazy about diaphragm, like... and others I will add when I think of them.
Words with a story: wonderful, via
*The first time I saw the movie from the Lemony Snicket (sp?) books, I remember being so content when I left. I loved how it was so imaginative and there was so much child like wonder. And then I realized it was full of wonder aka wonderful. The meaning of the word really hit home in that very moment, and I realized it wasn't just a synonym for good or hapy or pleasant. A character from Jitterbug Perfume (by Tom Robbins) argues, "There are no such things as synonyms!"
*The story for via (pronounced the British Vie-a, not V-a) is that I heard someone talking on NPR and they say vie-a and it took a moment to register what they were saying and it was probably the first time I was aware of the differences of English and the significance of the pronunciation.
Words I mispronounce: mountain (moun'in) or any word with a strong 't' in the ending syllable, it tends to get skipped or rounded out to a 'd', when (win), pillow (pellow). I find it funny that I mispronounce them, so I don't mind at all, unless I'm talking to someone academic/scholarly and then I feel a bit like a joke.
