are the short, quiet pronunciations of small grammar words such as to /tə/, of /əv/, and /ən/, can /kən/ and was /wəz/. Speakers use them in normal sentences and use the only for emphasis or at the end of a phrase. They give English its -timed rhythm.
What are weak forms?
Many small words in English have two pronunciations. The is the full sound you hear when the word is said alone or with emphasis: to /tuː/, can /kæn/, of /ɒv/. The is the quick, quiet version you hear in normal speech: to /tə/, can /kən/, of /əv/.
Most weak forms use the . The is reduced, and sometimes a is lost too: him becomes /ɪm/ and have becomes /əv/. Weak forms are not careless speech. They are the normal, correct way to say these words.
The common weak forms
The words with are grammar words: they carry little meaning of their own. The content words around them carry the message. Learn the list below in the sentence, not on its own.
- to: strong /tuː/ · to: weak /tə/ (I want to go.)
- of: strong /ɒv/ · of: weak /əv/ (a cup of tea)
- and: strong /ænd/ · and: weak /ən/ (fish and chips)
- can: strong /kæn/ · can: weak /kən/ (I can swim.)
- was: strong /wɒz/ · was: weak /wəz/ (He was late.)
- for: strong /fɔː/ · for: weak /fə/ (a present for you)
- have: strong /hæv/ · have: weak /əv/ (I have finished. / I should have gone.)
- the: before a consonant /ðə/ · the: before a vowel /ði/ (the book, the apple)
When to use the strong form
The is not wrong. It has special uses, and you need to know them. If you use a strong form everywhere, your speech sounds slow and heavy. If you use a in the wrong place, it can sound strange.
Use the strong form in four cases: when the word is at the end of a phrase, when you want to emphasise it, when it is in a short answer, and when you say the word on its own.
- At the end of a phrase: 'What are you looking for?' /fɔː/. 'Where are you from?' /frɒm/.
- For emphasis or contrast: 'I said FOR, not FROM.'
- In a short answer: 'Can you swim?' 'Yes, I can.' /kæn/.
- On its own: 'The word of is spelled o-f.'
Why weak forms matter: English rhythm
English is often described as -timed. This means the strong come at fairly regular beats, and the weak syllables are squeezed in between them. In real speech the timing is not perfect, but the idea helps. A sentence with few small words and a sentence with many take a similar time between the strong beats.
Look at these two sentences: 'Cats eat fish.' and 'The cats are eating the fish.' The second is longer, but you say it in a similar time because the extra words are weak and fast. If you give every word its , you lose this rhythm and your listener struggles to find the important words.
More weak forms to learn
Once the first group is easy, add these. They appear in almost every sentence you say in the Speaking test, so each one you learn is used again and again.
- them /ðəm/ or /əm/: I told them. (I told-əm.)
- you /jə/: What do you want? (What də-yə want?)
- would /wəd/: He would like tea.
- that /ðət/ as a conjunction: I think that it is late.
- some /səm/: Would you like some tea?
- from /frəm/, at /ət/, as /əz/, than /ðən/: bigger than me /ðən/.
A trap in writing: should have, not should of
In a phrase like 'should have' or 'could have', the word have is weak and sounds like /əv/: 'should have' is /ʃʊd əv/. It sounds exactly like 'should of', and that is why many people write 'should of' by mistake. The correct written form is always 'should have' (or the contraction 'should've'). Listen for the weak /əv/ in speech, but write have.
How to practise weak forms
Do not practise the in a list. Practise it inside a phrase, with the strong clear and the small words quick. Say the phrase while you tap on the strong words.
Start with phrases of two strong words and one weak word, then make the sentences longer.
- Tap the strong words: 'a CUP of TEA', 'FISH and CHIPS', 'I WANT to GO'.
- Say the weak words quickly and quietly, without stopping before them.
- Join the weak word to the word before: 'cup-əv-tea', 'want-tə-go'.
- Read a short text aloud and mark every weak form before you read.
Weak forms in contractions
Contractions are also . I'm, you're, it's, they've and I'll are common in both speech and informal writing. Notice that they sound weak as well: they're is /ðeə/ or /ðə/, you're is /jɔː/ or /jə/, and I'll is /aɪl/.
In the Speaking test, using contractions helps your speech sound natural. In Writing, avoid them in formal essays.
How to make the sound
- Relax your jaw and tongue for the . Do not round your lips.
- Say the strong word loud and clear, then say the weak word quickly and quietly: 'CUP of TEA'.
- Link the weak word to the word before it: cup-əv-tea.
- Keep a steady beat on the strong words as you speed up.
IELTS tip
In IELTS Speaking, strong and help you sound fluent and natural without speaking fast. Keep the key words clear and say the small words lightly. In IELTS Listening, expect speakers to use weak forms, so 'a cup of tea' may sound like 'a cuppa tea'.
