The 10 Hardest English Words to Pronounce

Unfortunately, when learning the English language – you can’t rely on spelling alone to tell you how to pronounce something correctly. There are lots of words that are spelled similarly but sound different when spoken. Since English words originate from lots of different languages, the English language has grown to incorporate a variety of pronunciation rules that can be quite confusing, even to a native speaker!

If you are learning English as a second language, there is no doubt that its extremely challenging to pick up the 20 vowel sounds and 25 consonant sounds that make up the language. Like all aspects of learning a language, if you want to get to grips with the many variations and inconsistencies between spelling and pronunciation, your best bet is to practise, practise, practise!

Why are so many English words difficult to pronounce?

Even for native English speakers, there are many words in the English language that don’t sound how we would imagine when we first read them on paper. Often, people have a hard time trying to dictate these words when they see them. There are many reasons for these discrepancies, some issues can be put down to the occurrence of:

  • Loan words

Although English is one of the most spoken languages in the world, many of the words are taken from other languages. Up to 80% of English vocabulary comes from another language including Latin, French, Italian, Spanish, Dutch, Japanese, Scandinavian, Sanskrit, Arabic, Russian, Hebrew, Persian and many more.

For example, the word ‘anonymous’ is taken from Greek, ‘loot’ comes from Hindi, ‘safari’ is taken from Arabic, and ‘karaoke’ from Japanese. Since so many words are taken directly or adapted from other languages, English spelling and pronunciation can lack a sense of consistency.

  • Orthography

Orthography refers to the conventional method of spelling in a language e.g. in most languages, if you see a word with the letter 'a' you automatically assume it is pronounced like ‘ay’. English uses opaque or deep orthography. Opaque orthography refers to the type of spelling where words are not always pronounced the way they are written. Instead, the rules of pronunciation change dependent on the word. Transparent orthography is where words are pronounced in the way they are spelled.

  • Confusion with our native language

If you know more than one language, it is natural to get confused when you start to learn another. People automatically read English words and draw connections to the other languages they know, assuming the words will be pronounced the same.

Many native Spanish and Russian speakers tend to emphasize the r sound. For example, a Spanish language speaker may pronounce the word 'car' as KARR, while English speaking people may pronounce it more like “CAH” or “CAW”. Furthermore, a Scottish person may accentuate the R like a Spanish person does, yet the effect will be totally different.

There are some sounds that prove difficult for non-native English speakers e.g. TH, Z, and KH offer pronunciation difficulties to learners of the English language. When we learn a language, we are using a lot of muscle memory, so we naturally try to incorporate what we know about other language pronunciation into learning a new language. For this reason, over time you will be able to learn new patterns.

How can I improve my pronunciation?

Learning a new language takes a lot of confidence and we know it can feel embarrassing when you mispronounce a word – especially in front of native speakers. However, some words are extremely difficult to pronounce and there is no reason to feel embarrassed. Give yourself some credit for the effort you’re putting in to learn something new, but take the time to learn some of the more difficult words.

It is important to remember that even native English speakers struggle with pronunciation and some words are so commonly mispronounced that the ‘correct’ pronunciation might begin to sound strange. Since the English language is always growing, there are many things that change based on region, culture and time period. Additionally, some people adhere strictly to grammar rules and some are less formal. Although you want to be as accurate as possible, the most important thing when speaking a new language is to make sure you communicate clearly and people can understand you.
