Are you pronouncing the "W" in "sword" or the "L" in "salmon"? Well, you're doing it wrong.
Hey, it's cute when kids say "liberry" instead of "library," but it's not so cute when you are an employment-seeking adult, or when you're trying to act snooty at cocktail parties.
(Trust me, I've found this out the hard way. How does one pronounce quinoa, again? Kee-no-uh?)
However, there are a few words that you can mispronounce without feeling all that embarrassed about, and that's because we've all been doing it wrong.
As a society, we sometimes make the mistake of arbitrarily deciding it's easier to say things our way instead of the correct way. Call it arrogance or convenience — call it whatever you want. I think our collective ignorance is worth that sensational feeling of having your mind blown when you finally realize the truth.
For all those budding wordsmiths out there: feel free to completely throw this in all of your friends' faces.
1. BANAL

You're putting emphasis on all the wrong parts.
2. LARVAE

English is crazy, man. I don't even know.
3. PRESTIGIOUS

I thought only prestigious people pronounced it "pre-STI-jus." I guess they're prestigious for a reason.
4. SHERBET

The collective unconscious invented an "R."

6. OFTEN

SPOILER ALERT: The "T" is silent.
7. PREROGATIVE

Bobby Brown started this trend.
8. AFFLUENT

We've been mispronouncing this word so long, dictionaries have begun to change the official pronunciation.
9. MISCHIEVOUS

The invisible "I."
10. CELTIC

Don't say it the wrong way in Boston!
11. LAMBASTE

Baste that lamb, you get it?
12. CACHE

This word is not French.
13. COMPTROLLER

No idea why that "P" is there either.
14. ELECTORAL

Stress the second syllable, not the third.
15. CHICANERY

Can we stop spelling "S"-sounding words with "C"s?
16. KIBOSH

I will continue to say this the wrong way for dramatic effect.

Oh, the controversy!
