Colonel

Native English speakers know that this 16th-century word, which is derived from Middle French, is pronounced ‘ker-nul.’ However, those learning English as a second language get confused by the first ‘o’ sounding like an ‘e,’ the ‘l’ that sounds like an ‘r,’ and the second ‘o,’ which is completely silent.
Worcestershire

Let’s be honest: this word is actually hard for native English-speakers to pronounce too. It looks like it’s pronounced ‘wor-cest-er-shi-er,’ but it actually retains is British-English pronunciation. Worcestershire sauce originated in the town of Worcester, England, and is pronounced ‘Wooster,’ while the term ‘shire’ is the British word for ‘county’ and sounds like the ending of ‘Hampshire.’ Therefore, the word is pronounced ‘WOOster-sher.’
Are you a good speller? Here are some of the hardest words to spell in the English language.
Mischievous

Like Worcestershire, ‘mischievous’ is one of those hard words to pronounce that many have trouble saying. In fact, you’ve probably heard people pronouncing the word as ‘mis-CHEEVE-ee-us,’ when it’s actually a three-syllable word pronounced ‘MIS-chiv-us.’ The problem lies in the fact that the old form of the word was spelled with an extra ‘i’ at the end, which was standard until the 1700s.
