Words You've Mispronounced Due to Lack of Use

I read years ago about "Geek Problems" or something and one was not having any idea how certain words are actually pronounced because you never hear them aloud or use them often. Anybody have any words like this?
I found out a couple of days ago that I've been mispronouncing "Posthumous" all of my life.

 

Uhhhh, i do have a few things but.... damn I've forgotten. I think how to pronounce Chinese names was one for a while. Also, the letters like é or æ still allude me.

 

Niger.

 

Usually foreign words than come into English use, such as Latin. Recently "a priori", for one.

When I was in middle school, my friend pronounced 'grand prix' as 'grand pricks' and the whole class laughed at her. I still feel sorry for her lol.

 

There's a word that, whenever I see it, I always read phonetically in my head so I won't say it the way it's spelled. Surprisingly, it's not "colonel" (even though that is equally ridiculous) but I can't remember what it is.

i laughed
i'm a grand prix

 

English not being my mother tongue, all the freaking time. The latest would be "caveat". As for French words it does happen but it' s too rare for me to think of any exemple.

 

Subtle.

I used to say subtle but read it as sub-tul. I never made the connection that they were the same word and that I was mispronouncing one until a year or so ago.

 

Only a few. Mostly foreign shiz.

Cognac - cog-nack
Curacao - cure-a-chao (only found out the correct pronunciation the other day >_>)

Facade - fack-aid ...

 

Pfft. The unsubtle sub-buttle!

 

Hmm. I can't think of very many at the moment, but occasionally I'll say 'statistics' or 'preposterous' wrong. And when I was little I would say 'pacific' when I was trying to say the word specific.

 

Microwave .

 

Explicit used to be one for me, I'd say it with a hard c ("explikit").

EDIT: I JUST FOUND ANOTHER ONE

 

Epitome (Ep-eh-tome)

 

The whole 'gif/jif' debacle.

 

First time I pronounced debut aloud, I said da butt. STORY END.

You looke like a meekrowave yais i theenk so khand KHAI DUNT WANT KHER TO BRAKE MY VEENDOH!
