How to Pronounce English Contractions, and When You Cannot Use Them

Contractions are not informal English. Newsreaders, lecturers and business people use them constantly in speech, and a learner who says "I am not sure" and "it is not possible" in every sentence sounds stiff even when the grammar is perfect.

Most contractions are easy to pronounce once you know them. A few create sounds learners do not expect, such as the syllabic /n/ in didn't and the vowel of won't, and there are places where a contraction is grammatically impossible. This guide covers all three.

Pronoun + be, will, have and would

Two things to notice. First, several contractions are homophones of other words, which is why native speakers confuse you're and your in writing: they sound the same. Second, 's and 'd are ambiguous:

• He's can be he is or he has: "He's going" (is), "He's gone" (has).
• I'd can be I would or I had: "I'd go" (would), "I'd gone" (had).

The word that follows always resolves it. A base verb means would; a past participle means had.

Negative contractions and the syllabic n

The small mark under n̩ means the /n/ forms a syllable on its own, with no vowel before it. This is the part learners find strange. In didn't, the tongue touches the ridge behind the teeth for /d/ and then stays there while the air is released through the nose for /n/. There is no "did-ent". The same happens in couldn't, wouldn't, shouldn't, isn't, wasn't and doesn't.

To practise, say did, hold your tongue on the ridge at the end, then hum through your nose without moving it: did-nnn. Add a light /t/ at the end. That is didn't.

Won't and want

Won't /wəʊnt/ and want /wɒnt/ (American /wɑːnt/) are one of the most important pairs in the language, because confusing them reverses the meaning: "I won't go" versus "I want to go". The difference is the vowel:

• won't has the diphthong of go and don't: "wohnt"
• want has the short vowel of hot (British) or father (American)

A useful trick: won't rhymes with don't. If you can say "I don't" correctly, change one sound and you have "I won't".

Where contractions are impossible

A contraction cannot be the last stressed word in a clause. The contracted word needs something after it to lean on.

Negative contractions are an exception: they carry their own stress, so "No, I'm not" and "No, I don't" are perfectly normal at the end of a sentence.

Contractions with nouns are common in speech but written less often: "The car's outside", "My sister'll call you", "The meeting's been cancelled". Learners can use these freely when speaking.

Informal reductions: gonna, wanna, gotta

A second group of reduced forms is more informal than standard contractions. You will hear them constantly in films and conversation, including from educated speakers, but they are usually avoided in writing.

Should learners use these? Recognising them is essential. Producing them is optional. If you use gonna in informal speech with correct rhythm, it sounds natural; if you use it with careful, even rhythm, it sounds odd. A good approach is to use them only after your weak forms and sentence stress are already natural.

Practice dialogue

Read this aloud, contracting everything that can be contracted. The underlined words are where learners most often use full forms.

A: I'm not sure we'll finish today. You're still waiting for the report, aren't you?
B: Yes, I am. It should've arrived yesterday, but it didn't. I don't know why.
A: Well, I won't leave until it's done. I'd rather stay late than come back tomorrow.

Notice should've, which sounds exactly like "should of", /ˈʃʊdəv/. That is why native speakers sometimes write "should of" by mistake.

Frequently asked questions

Are contractions too informal for exams like IELTS or TOEFL?

No. In speaking tests, contractions are expected and sound natural. Avoiding them makes speech sound stiff. In formal academic writing, they are usually avoided.

How do I pronounce didn't without adding a vowel?

Keep the tongue tip on the ridge behind your upper teeth after the /d/ and release the air through your nose for /n/. There is no vowel between d and n. Practise by saying did, holding the tongue in place, and humming.

What is the difference between won't and want?

The vowel. Won't rhymes with don't and has the diphthong of go. Want has the short vowel of hot in British English or of father in American English.
