Learners most often mispronounce words because the spelling misleads them. Some letters are silent, some disappear in natural speech, some words have unexpected , and some are not what the letters suggest. Forty common examples are grouped below, each with its British English sounds.
Why these words go wrong
English spelling records the history of a word, not how it sounds today. Letters stay on the page after they have stopped being said, and shrink in everyday speech. A learner who says every letter will often be using a pronunciation that no native speaker uses.
The forty words below are grouped by the reason they cause trouble. The shows the usual British English pronunciation. The capital letters show the strong syllable. Learn each word with its group, because the reason helps you remember it and apply it to other words.
Group 1: syllables that disappear
In these words, a that you can see in the spelling is not said in normal speech. The word is shorter than it looks. Count the you hear, not the vowels you see.
- Wednesday /ˈwenzdeɪ/: two syllables, WENZ-day. There is no d before the n.
- comfortable /ˈkʌmftəbl/: three syllables, KUMF-tuh-bl, not 'com-for-ta-ble'.
- vegetable /ˈvedʒtəbl/: three syllables, VEDJ-tuh-bl.
- business /ˈbɪznəs/: two syllables, BIZ-nuhs, not 'busy-ness'.
- chocolate /ˈtʃɒklət/: two syllables, CHOK-luht.
- different /ˈdɪfrənt/: two syllables, DIF-ruhnt.
- interesting /ˈɪntrəstɪŋ/: three syllables, IN-truh-sting.
- February /ˈfebruəri/: say the first r, FEB-roo-uh-ri.
Group 2: silent letters
Silent letters are the best-known problem. There is no rule that predicts them completely, but some patterns help: kn- at the start (knowledge), ps- at the start (psychology), -mb at the end (climb), and -stle or -sten in the middle (castle, listen).
- debt /det/ and doubt /daʊt/: the b is silent.
- receipt /rɪˈsiːt/: the p is silent.
- island /ˈaɪlənd/: the s is silent.
- castle /ˈkɑːsl/ and listen /ˈlɪsn/: the t is silent.
- knowledge /ˈnɒlɪdʒ/: the k is silent.
- psychology /saɪˈkɒlədʒi/: the p is silent.
- queue /kjuː/: it sounds exactly like the letter Q.
- foreign /ˈfɒrən/: the g is silent.
Group 3: stress in the wrong place
means the strong of a word: longer, louder and clearer. If it moves, the word can sound like a different word, and listeners work harder to understand you. Dictionaries mark it with the sign ˈ before the strong syllable.
- photograph /ˈfəʊtəɡrɑːf/, but photographer /fəˈtɒɡrəfə/: the stress moves.
- economy /ɪˈkɒnəmi/: the strong syllable is CON.
- hotel /həʊˈtel/ and police /pəˈliːs/: the strong syllable is the second.
- develop /dɪˈveləp/: the strong syllable is VEL, and there is no stress on the last syllable.
- career /kəˈrɪə/: the strong syllable is the second, RI.
- technique /tekˈniːk/: the strong syllable is NIQUE.
- advertisement /ədˈvɜːtɪsmənt/: the strong syllable is VER.
- environment /ɪnˈvaɪrənmənt/: the strong syllable is VI, and the n before the second part must be said.
Group 4: vowels that surprise you
In these words the letters suggest one and the word uses another. Trust the , not the spelling.
- pronunciation /prəˌnʌnsiˈeɪʃn/: the second is NUN, not 'noun'. It is not the same vowel as in the verb pronounce.
- clothes /kləʊðz/: say the th, or in fast speech the shorter /kləʊz/.
- iron /ˈaɪən/: the r is silent in British English; two syllables, EYE-uhn.
- schedule /ˈʃedjuːl/: in British English it starts with sh.
- sugar /ˈʃʊɡə/: it starts with sh.
- mischievous /ˈmɪstʃɪvəs/: three syllables, MIS-chi-vuhs.
- height /haɪt/: it ends in t, not th.
- recipe /ˈresəpi/: the last e is said, RES-uh-pee.
Group 5: sounds that are easy to swap
The last group contains words where a sound is changed, added or lost. These are the words learners notice their listeners misunderstand.
- library /ˈlaɪbrəri/: say the r after b, LIE-bruh-ri, not 'lie-berry'.
- ask /ɑːsk/: the s comes before the k, not 'aks'.
- specific /spəˈsɪfɪk/: begin with spuh-, not 'pacific'.
- temperature /ˈtemprətʃə/: three , TEM-pruh-chuh.
- literature /ˈlɪtrətʃə/: three syllables, LIT-ruh-chuh.
- usually /ˈjuːʒuəli/: the middle sound is , as in measure.
- subtle /ˈsʌtl/: the b is silent.
- salmon /ˈsæmən/: the l is silent.
How to learn them
Do not try to learn all forty at once. Choose five that you use often in your own speaking and writing topics, such as environment, economy, pronunciation, different and interesting. Look each one up in a dictionary that has audio, listen twice, then say it three times in a full sentence.
Keep a short list of your own mispronounced words. When a teacher or a friend does not understand you, write down the word and its . That list is worth more than any general list, because it contains your words.
IELTS tip
Most of these words are ordinary IELTS vocabulary: environment, economy, different, interesting, knowledge, literature, temperature. Check the and the count of the 10 words you use most before you speak. Saying them naturally helps listeners follow your ideas without effort.
