I think the word 'duh' (doh?) came from The Simpons tv show. It is quite a useful word. Here a few of my duh word moments.
Hyperbole, a word that I mispronounced in my head every time I read it until I was well into my twenties. I never embarrassed myself by saying the word out loud until I learnt it was not said hyperbowl.
Hermione, oh so tragic. While I know the word now, I am still unsure of the precise pronunciation. Do the lips go out after the m?
Eloise. It defies the vowel sound pronunciation I learnt as a kid. One day the light bulb moment arrived.
Place names remain problematic. Before we went to Vietnam, I told a Vietnamese born workmate that we were going to stay a night in Hue. Me saying Whoee, had him express a very blank face.
Before we went to Japan, at a party a Japanese guy asked where we were staying in Tokyo. I replied Uno, mispronouncing Ueno. I tried some pronunciation variations and he finally worked it out.
Once up in the north of Japan, I put the wrong emPHAsis on the wrong sylLABle of Aomori. Place names are fraught.
I did well enough in England, knowing enough to pronounce Cholmondeley correctly and how to say the suffix 'shire. I even managed to understand Geordie, slightly toned down for my benefit, the toning down which invariable disappeared after a few drinks by our various hosts. English/Eastern Europe accent in London, no problem. Sad that we met only one English English person in London. I'm afraid the broad Lancashire accent got me though. I had to call on R to help, and even being English born, he struggled.
Food menus are the perfect way to embarrass yourself. I do now confidently pronounce bruschetta correctly and confidently, although few others seem to in Australia. If I don't know, I will say, 'Sorry, I am not sure how to say this', as I point. I would rather do that than get the word wrong.
Many of you are or were school teachers. At least teach your kids about a few of these hard words. Although while I have never had anything to do with Harry Potter books or films, I don't think kids will have such a problem with Hermione now.
