Are you sick of having trouble pronouncing hard English words? We are here to help you master the most challenging words, from common words with silent letters to tongue twisters that leave you speechless, so stick around!

One of the most crucial elements of learning a new language is pronunciation. Word mispronunciation can result in a lot of misunderstandings, some of which can be amusing or even embarrassing. So it makes perfect sense that as an English learner, you would want to perfect your pronunciation so that you sound as natural as possible.

A lot of people search for why is English hard to learn, one main reason is that English has a number of words that can be challenging to pronounce, despite the fact that it may not seem like the most difficult language to do so. This is primarily due to the English language’s word-stuffing from other languages.

You may have noticed that there is a discrepancy between the pronunciation and spelling of some words in English. Sometimes, a word’s spelling or pronunciation has nothing to do with one another. In English, the phonemes (sounds) and the graphemes (written words) don’t always match up linguistically.

This is primarily due to the fact that English borrows words from many other languages, including French, Latin, Greek, and German. For instance, “vacuum” is derived from the Latin word “vacuus,” which means “empty.”

We have structured this guide in the form of a long list so that you can learn the hardest English words and their pronunciation in an organized manner. But, before we get into the list, here is a course recommendation for you.
