Vocabulary and grammar for the Speaking test
How to show lexical range and grammatical flexibility in IELTS Speaking - paraphrase, collocation, natural idiomatic language and the structures that lift your score.
Lexical Resource and Grammatical Range and Accuracy make up half of your Speaking score. As in Writing, the route to a higher band is not rare words and tangled sentences. It is flexibility: being able to say what you mean in more than one way, with language that fits the situation, and with few enough errors that the listener never has to work to understand you.
Part 1: Lexical Resource
What examiners notice
- Range: can you talk about many topics without running out of words?
- Precision: exhausted rather than very tired; a stroll rather than a walk.
- Collocation: words in natural combinations.
- Idiomatic language: everyday natural expressions and phrasal verbs.
- Paraphrase: getting round a gap.
Paraphrase: the essential skill
Every speaker, at every level, sometimes cannot find a word. Band 6 speakers ‘generally paraphrase successfully’; Band 7 and above do it ‘effectively’. Practise these moves until they are automatic.
| Move | Frame | Example |
|---|---|---|
| Category + detail | It’s a kind of… that… | ‘It’s a kind of shop that only sells tools and paint.’ (hardware store) |
| Function | It’s something you use to… | ‘It’s something you use to tighten bolts.’ (spanner) |
| Comparison | It’s like a… but… | ‘It’s like a small lake, but man-made.’ (reservoir) |
| Opposite | It’s the opposite of… | ‘He’s the opposite of generous.’ (mean) |
| Example | …things like… | ‘…things like knives, forks and spoons.’ (cutlery) |
| Approximate word | sort of / more or less / -ish | ‘It was a sort of orangey-brown.’ |
Exercise: take ten everyday objects and describe each in English without using its name. Then check the real word.
Upgrading common words
| Overused | Alternatives (choose by meaning) |
|---|---|
| good | enjoyable, impressive, useful, convenient, rewarding, reliable, decent |
| bad | disappointing, unpleasant, harmful, inconvenient, stressful, awful |
| nice | friendly, pleasant, cosy, attractive, thoughtful |
| big | huge, enormous, spacious, significant, major |
| small | tiny, compact, cramped, minor |
| very tired / happy / angry | exhausted / delighted, thrilled / furious |
| important | essential, crucial, a priority, a big part of my life |
| interesting | fascinating, absorbing, thought-provoking, gripping |
| a lot of | plenty of, loads of (informal), a great deal of, countless |
| I think | I reckon, I’d say, it seems to me, as far as I can tell |
Do not replace every simple word. A natural speaker mixes plain and precise vocabulary.
Collocations and chunks for speaking
- make a decision / an effort / a difference / a mistake / progress
- take a break / a risk / responsibility / part in / advantage of
- have a chat / a look / a go / second thoughts / a lot in common
- keep in touch / fit / an eye on / track of
- get on with / used to / into (a hobby) / rid of / round to
- spend time + -ing; waste time on; run out of time; in my spare time
- heavy traffic, strong coffee, a close friend, a tight budget, a busy schedule, a narrow escape
Natural idiomatic language
Useful, common and safe:
| Expression | Meaning | Example |
|---|---|---|
| not my cup of tea | not something I like | Opera isn’t really my cup of tea. |
| once in a blue moon | very rarely | I go to the cinema once in a blue moon. |
| cost an arm and a leg | be very expensive | The flights cost an arm and a leg. |
| get the hang of | learn how to do | It took me a while to get the hang of it. |
| from scratch | from the beginning | I made the cake from scratch. |
| on the spur of the moment | without planning | We booked it on the spur of the moment. |
| in two minds | undecided | I’m in two minds about moving. |
| a blessing in disguise | something that seems bad but turns out well | Missing that train was a blessing in disguise. |
| learn the hard way | learn from a bad experience | I learned the hard way to back up my files. |
| go over my head | be too difficult to understand | A lot of it went over my head. |
| second nature | automatic | Driving is second nature to me now. |
| read between the lines | understand what is not said directly | You have to read between the lines. |
Use one or two where they fit. A string of idioms sounds forced, and an idiom used slightly wrongly (‘it rains dogs and cats’) is worse than none.
Topic vocabulary
Build a small bank for each of the common Part 2 and 3 themes: education, work, technology, environment, health, media, travel, family, cities, culture. Ten to fifteen phrases for each is enough. Record them in sentences about your own life, because personalised vocabulary is easier to recall under pressure.
Part 2: Grammatical Range and Accuracy
Range: structures to bring into your speech
You do not need to force complicated grammar. You need to answer questions in a way that naturally calls for different structures.
1. A mix of tenses
| Situation | Structures |
|---|---|
| Habits | present simple, tend to, will for typical behaviour |
| Now / temporary | present continuous (I’m working on a project at the moment) |
| Past events | past simple, past continuous, past perfect |
| Past habits | used to, would |
| Experience / change | present perfect (I’ve never tried it / It’s become much busier) |
| Duration up to now | present perfect continuous (I’ve been learning Spanish for two years) |
| Future | going to, will, present continuous, might, I’m hoping to |
2. Conditionals
- First: If I get the grades, I’ll apply for a master’s.
- Second: If I had more space, I’d get a dog.
- Third: If I hadn’t taken that course, I’d never have met her.
- Mixed: If I’d practised more as a child, I’d be much better now.
Part 3 ‘what if’ questions and Part 1 ‘would you like’ questions invite these.
3. Relative clauses
- The man who lives upstairs was learning the drums.
- It’s a place where you can spend time without buying anything.
- I stopped when I was eleven, which I regret now. (commenting on a whole idea: very natural and useful)
4. Comparatives
- It’s nowhere near as busy as it used to be.
- The more I practised, the easier it got.
- far better, slightly cheaper, twice as long, by far the best
5. Modals
- Possibility: might, may, could, may well
- Deduction: must be, can’t be, must have been
- Advice / criticism: should, ought to, should have + past participle
- Ability: managed to, was able to, couldn’t
6. Passives
- It was built in the 1950s. / I was given it for my birthday. / The area has been completely redeveloped.
7. Reported speech and questions
- He said that if I was old enough to ride it, I was old enough to mend it.
- She asked me whether I’d ever tried it.
8. Emphasis (cleft sentences)
- What I love about it is the atmosphere.
- The thing that surprised me was how quiet it was.
- It was my grandfather who taught me.
These are common in fluent speech and are an easy way to add range.
Accuracy: the errors that matter most
| Error | ✗ | ✓ |
|---|---|---|
| Third person -s | She work in a bank. | She works in a bank. |
| Past tense slips | Yesterday I go… | Yesterday I went… |
| Articles | I am student. / I like the music. | I am a student. / I like music. |
| Plurals | many informations, two childs | a lot of information, two children |
| Prepositions | depend of, married with, good in | depend on, married to, good at |
| Word order in indirect questions | I don’t know where is it. | I don’t know where it is. |
| -ed / -ing adjectives | I am boring in class. | I am bored in class. |
| Comparatives | more better, more cheap | better, cheaper |
| used to | I am used to play (for past habit) | I used to play |
| Subject pronouns | My brother he works… | My brother works… |
Tense consistency is the most audible problem. If you start a story in the past, stay in the past. Before the test, practise telling a two-minute past story and listen only for verbs.
Accuracy versus fluency
Do not let the fear of mistakes stop you speaking. A fluent answer with a few errors scores better than a perfect sentence followed by silence. The balance to aim for: speak freely, monitor lightly, correct only what matters.
Practice routine
- Record and transcribe. Record a two-minute answer, write down exactly what you said, and mark every error and every repeated word. Rewrite the transcript, improving vocabulary and grammar, then say the improved version aloud. Do this twice a week.
- Structure of the day. Choose one structure (for example, the second conditional or used to) and use it at least five times in that day’s practice.
- Steal from samples. From each sample answer in the practice tests, take three expressions and use them in your own answers within twenty-four hours.
- Paraphrase game (above), five objects a day.
Key points
- Flexibility, precision and collocation matter more than rare words.
- Paraphrase smoothly when a word will not come.
- Use everyday idiomatic expressions and phrasal verbs sparingly and accurately.
- Let your answers bring in a range of tenses, conditionals, relative clauses and modals.
- Fix high-frequency errors: -s endings, past tense, articles, prepositions.
- Speak freely first; correct lightly.
