Vocabulary: it’s rarely about knowing more words.

Lexical resource is a quarter of your Speaking mark. What lifts it isn’t a bigger dictionary, it’s the right collocation, the right register, and the right word for the connection you’re making.

Why this matters. Most candidates who plateau at Band 6.5 don’t lack words; they reuse plain ones, miss the natural collocation, and reach for the same three linkers. Band 7 is collocation and flexibility; Band 8 is precision. This page shows the same idea climbing the bands, the cohesive devices that signal range, and how to link ideas with the right clause rather than stringing simple sentences together.

01Upgrade by band

The same idea, raised.

Here is one answer about education at three bands. The thinking doesn’t change, the words do. Switch the band and watch what lifts it.

I think education is very important because it helps people get good jobs. Students should study hard and learn many subjects.

Accurate, but plain. important, good jobs, study subjects, nothing wrong, nothing that shows range.

I believe quality education plays a crucial role in career advancement. Students who pursue academic excellence and develop critical thinking skills tend to achieve better professional outcomes.

Same ideas, better words. plays a crucial role (collocation), pursue academic excellence (precise verb), professional outcomes (formal register).

I'd argue that educational qualifications are a decisive factor in career advancement, though not the only one. Students who cultivate genuine intellectual curiosity, rather than simply accumulating credentials, tend to fare better in the long run.

Not bigger words, more precise ones, a qualification (though not the only one) and a natural idiom (fare better). Refinement, not revolution.

Register works both ways

Formal vocabulary in a casual Part 1 answer sounds memorised, not impressive. “I derive considerable satisfaction from culinary pursuits” in answer to do you like cooking? is worse than “I really enjoy it.” Save the formal register for Part 3.

02Cohesive devices by function

Vary the connection, not just the word.

Linkers are graded too. Band 6 is stuck in the basic column; Band 7 moves flexibly through the intermediate; Band 8 draws from all three and picks the most precise marker, not the most impressive. Choose a band to see its column.

Emphasisingvery, really, quiteparticularly, especially, notablyremarkably, significantly, crucially

Don’t memorise the advanced column and deploy it wholesale, and don’t carpet-bomb “Firstly… Moreover… Furthermore…”. Reusing one function’s markers reads as limited range. Reach for a different function: an example, then a contrast, then a conclusion.

03Link with the right clause

Two simple sentences become one good one.

Range isn’t only words, it’s how you join ideas. Each relationship between two ideas has a clause type that carries it. Combining is itself a Band 7+ signal.

To…Use a…WithFor example
Add detail to a nounrelative clausewho · which · thatMy hometown, which sits on the coast, depends on tourism.
Weigh two sidesconcession clausealthough · while · despiteAlthough technology saves time, it can isolate people.
Show purpose or resultpurpose / result clauseso that · so… thatCities are redesigning roads so that cycling feels safer.
Hypothesiseconditionalif · unlessIf governments invested earlier, the costs would fall.

Choppy, simple sentences

I like my city. It is by the sea. It has good transport. The transport is cheap.

Combined, one complex sentence

I’m fond of my city, which sits by the sea and has cheap, reliable transport.

Range you can actually reach for

A word list you’ve read isn’t a word you can use under pressure.

The gap between recognising a word and producing it in the test is exactly what a lesson closes.

In a lesson we work your real answers: I catch the plain word, suggest the precise one, and drill the collocations until they arrive on their own, then push you to vary the connection rather than repeat it. Lessons are £20 for fifty minutes, one to one, in proper British English; the first step is a free 25-minute introduction.
