How to use this list of hard English words to pronounce

These hardest English words to pronounce are listed with broad British dictionary-style IPA, so you always have the same reference, plus American alternatives where the difference is useful. They are accepted pronunciations, not the only correct ones. /ˈ/ comes before the main stressed syllable and /ˌ/ marks secondary stress. /ə/ is schwa, the relaxed vowel at the end of sofa. Anything between slashes is a sound, not a spelling.

Read the tip, listen to a dictionary recording, and say the word without looking at the spelling. Then look at the spelling and try again. If a symbol is new to you, focus on the recording and the mouth movement. Respellings like WUSS are only rough reminders. IPA and audio are more reliable.

Hard English words with silent letters

A silent letter has no sound of its own in the pronunciation shown. Don't slip in a tiny vowel to make room for it. Practise how the word sounds first: debt is one syllable, and receipt ends in /t/. Some related words behave differently, so treat these as examples, not a rule that the same letter is always silent.

WordIPA: UK; US where differentHow to say it
debt/det/Go straight from the vowel to /t/. Leave out the b.
doubt/daʊt/Use the vowel glide of out, then /t/. No b.
receipt/rɪˈsiːt/Stress the second syllable and keep the p silent.
island/ˈaɪlənd/Start like eye, then a light lənd. No s.
Wednesday/ˈwenzdeɪ/Say two syllables. Don't read every written vowel.
knight/naɪt/It sounds like night. Begin with /n/.
salmon/ˈsæmən/Move from the first vowel to /m/. No l.
subtle/ˈsʌtəl/Say two syllables, stressing the first. No b.
psychologyUK /saɪˈkɒlədʒi/ · US /saɪˈkɑlədʒi/Begin with /s/ and stress the syllable with /kɒ/.

Say the silent-letter words in context

A handy check is to record the word next to a simpler rhyme: debt with net, doubt with out, and knight with light. If the spelling tempts you to add a sound the rhyme doesn't have, cover the word again. Say the pair twice, then go back to the sentence.

English words with the most misleading spelling

You can't sound these words out letter by letter. Colonel is pronounced like kernel, and nothing in the spelling tells you that. The ending -ough has several pronunciations, so learning one example won't help you with the others. Group the words by the vowel and ending you actually hear, then practise a new sentence for each.

WordIPA: UK; US where differentHow to say it
colonelUK /ˈkɜːnəl/ · US /ˈkɝnəl/Say kernel. American /ˈkɝnəl/ keeps the r colouring.
WorcestershireUK /ˈwʊstəʃə/ · US /ˈwʊstɚʃɚ/One common British form: WUSS-tuh-shuh. American forms often include r.
queue/kjuː/One syllable, like the letter Q. No extra vowels.
choirUK /ˈkwaɪə/ · US /ˈkwaɪɚ/Begin /kw/, then the vowel of eye and a light ending.
yachtUK /jɒt/ · US /jɑt/One syllable. Start with the sound at the beginning of yes.
draughtUK /drɑːft/ · US /dræft/Finish with /ft/. Here gh is /f/, not silent.
thoughUK /ðəʊ/ · US /ðoʊ/Use voiced th and a vowel glide. No /f/ at the end.
through/θruː/Use voiceless th, then r and the vowel of blue.
thoroughUK /ˈθʌrə/ · US /ˈθɝoʊ/Two syllables in this British form; American often /ˈθɝoʊ/.

For Worcestershire, learn the name on its own first, then add sauce. Don't invent a "chest" syllable from the letters in the middle. Merriam-Webster lists several pronunciations, so someone who says the ending differently isn't wrong. Place names and borrowed words often keep regional variants.

How to pronounce th and hard consonant clusters

A consonant cluster is a group of consonants with no vowel between them. For /θ/, rest the tip of your tongue lightly at or just between your front teeth and let air flow out. For /ð/, use the same position and add your voice. In sixth, move through /k/, /s/ and /θ/ without adding an extra syllable. Start slowly and keep your jaw relaxed.

WordIPA: careful UK; US where differentHow to say it
sixth/sɪksθ/Build /θ/, then /sθ/, then /ksθ/, and join it to six.
sixths/sɪksθs/Add the plural /s/ gently after sixth. Don't rush it.
three/θriː/Move directly from tongue-at-teeth /θ/ into English /r/.
clothesUK /kləʊðz/ · US /kloʊðz/A careful form has /ðz/. Shorter forms are also common.
months/mʌnθs/Finish with tongue at the teeth, then slide toward /s/.
strengths/streŋθs/Keep /ŋ/ at the back. A form with /k/ is also heard.
crisps/krɪsps/Close the lips briefly for /p/ between two /s/ sounds.
askedUK /ɑːskt/ · US /æskt/One syllable. Finish /skt/ without an extra vowel.
texts/teksts/Keep the vowel short and build the final /ksts/ slowly.

Native speakers simplify some clusters in everyday conversation too. The careful forms above are a starting point. You don't have to say every sound in full when you speak fast. Keep the word recognisable and keep its grammatical ending, and compare yourself with a real recording in the variety you have chosen. The th guide has a slower ladder that takes you from single sounds to sentences.

Why are squirrel, rural and similar words so hard to pronounce?

Quick switches between /r/, /l/ and vowels can be harder than the sounds on their own. For English /r/, don't tap your tongue against the roof of your mouth. The exact tongue shape varies from speaker to speaker. For /l/, the tip usually touches the ridge behind your upper teeth. Practise the switch with a small movement instead of pulling your whole jaw back.

WordIPA: UK; US where differentHow to say it
squirrelUK /ˈskwɪrəl/ · US /ˈskwɝəl/Start with /skw/, then a short vowel and the move from r to l.
ruralUK /ˈrʊərəl/ · US /ˈrʊrəl/Go from r to the vowel to r with control. Don't rush.
worldUK /wɜːld/ · US /wɝld/Round your lips for /w/ and finish /ld/ in one syllable.
regularlyUK /ˈreɡjələli/ · US /ˈreɡjəlɚli/Stress the first syllable and keep the later vowels light.
FebruaryUK /ˈfebruəri/ · US /ˈfebrəˌweri/One accepted form keeps both r sounds. Shorter forms also exist.
brewery/ˈbruːəri/Keep the middle vowel movement smooth and the ending light.
jewellery/ˈdʒuːəlri/British form. American jewelry has a different spelling and rhythm.
mirrorUK /ˈmɪrə/ · US /ˈmɪrɚ/The British form ends in schwa. American speech keeps the final r.
libraryUK /ˈlaɪbrəri/ · US /ˈlaɪbreri/Stress the first syllable and keep the second vowel light.

In American English, squirrel can be squeezed towards one syllable, while the British model shown here has two. Rural also has accepted vowel differences. Don't compare an American recording with a British transcription and call the difference a mistake. The American vs British comparison explains these model choices.

Hard words where the stress catches you out

Stress in the wrong place can make a familiar word hard to recognise. A stressed syllable usually stands out through pitch, length and vowel quality. It isn't just louder. Tap the main beat on the table, say the rest more lightly, then stop tapping. Check related words one by one, because adding a suffix can move the strongest syllable.

WordIPA: UK; US where differentHow to say it
anemone/əˈneməni/Four syllables. Stress NEM and keep the vowels around it light.
mischievousUK /ˈmɪstʃɪvəs/ · US /ˈmɪstʃəvəs/Use three syllables in this standard dictionary form.
comfortableUK /ˈkʌmftəbəl/ · US /ˈkʌmftɚbəl/A common three-syllable form. Stress the first syllable.
vegetable/ˈvedʒtəbəl/Three syllables. Don't give every written vowel its own beat.
photographUK /ˈfəʊtəɡrɑːf/ · US /ˈfoʊtəɡræf/Stress the first syllable and finish with /f/.
photographyUK /fəˈtɒɡrəfi/ · US /fəˈtɑɡrəfi/Move the main stress to the second syllable.
photographicUK /ˌfəʊtəˈɡræfɪk/ · US /ˌfoʊtəˈɡræfɪk/The main stress falls on GRAPH. The first beat is weaker.
epitome/ɪˈpɪtəmi/Four syllables. The final e is pronounced /i/.
entrepreneurUK /ˌɒntrəprəˈnɜː/ · US /ˌɑntrəprəˈnɝ/Give the last syllable the main stress in this model.

Practise stress and movement together

The word-stress rules help you spot useful suffix patterns, but check new words with audio. A rule is a good guess, not a reason to ignore an established pronunciation. In comfortable and February, how many syllables get squeezed together depends on the speaker and the speed.

How to remember hard words when you actually speak

  • Choose three words from one challenge group and listen to each twice.
  • Say each word three times slowly, using only one correction cue.
  • Record a short phrase, then a complete sentence.
  • Wait until later in the day and say the words without reading them.
  • The next day, mix one old word with two new words.

If you can only say a word after several tries, keep it for the next session. If you can use it in a new sentence without stopping, move on. The word and phoneme feedback from the pronunciation test helps you look into a problem that keeps coming back. Then listen to your recording and decide what to change. The test scores against a General American reference, so a British form such as mirror without the final r may score lower even though it isn't wrong.

Frequently asked questions

What is the hardest English word to pronounce?

No single word is the hardest for everyone. Your first language, the words you already know and the variety of English you are learning all make a difference. Worcestershire breaks the spelling rules, sixths is a pile of consonants, and rural is a quick tongue switch. Focus on the words that trip you up in your own conversations. Popular "hardest words" lists are not scientific rankings.

How do you pronounce Worcestershire?

One common British pronunciation is /ˈwʊstəʃə/, roughly WUSS-tuh-shuh. American pronunciations often keep the r sounds and vary in the last syllable. Start with Worcester, then add the ending gently. Listen to a dictionary recording in the variety you are learning, because several forms are accepted, especially between British and American English.

Why is colonel pronounced like kernel?

Colonel and kernel sound the same in the reference varieties used here. The odd spelling comes from the word's borrowing history: the pronunciation with r stayed, while the spelling came to look more like the Italian original. In practice, learn colonel as a whole spoken word and practise it next to kernel.

How do you pronounce sixths?

Use /sɪksθs/ as a careful practice target and build the final cluster in stages without adding vowels. In everyday speech, native speakers simplify hard clusters too, so you don't have to pronounce every consonant at full strength. Your goal is a word people recognise in context. Start with sixth, add the plural ending, and only speed up when the movement feels comfortable.

Are British and American pronunciations both correct?

Yes. Many words have established regional versions, with differences in vowels, r sounds and the number of syllables. Pick one labelled dictionary model for practice, and listen to other varieties so you can understand them. A pronunciation checker may prefer its own reference, so a mismatch on its own doesn't prove your pronunciation is wrong.

Do tongue twisters help with hard words to pronounce?

They can give you extra coordination practice once you can already say the target words correctly. Start with a short phrase at a comfortable pace and keep the key contrast clear. Racing through a tongue twister can lock in the wrong sounds. To make it useful in daily life, also practise the same word in a sentence you might really say.
