PTE Academic vocabulary: high-frequency words
A strong, flexible vocabulary is one of the highest-leverage things you can build for the PTE Academic and PTE Core. This page gives you grouped, high-frequency word lists with quick meanings and usage, plus the words that matter most for specific tasks like Describe Image and Read Aloud. Learn these, use them in your own sentences, and you will lift several scores at once.
Why vocabulary matters across all four PTE skills
Vocabulary is an enabling skill in PTE, which means it feeds into more than one of your communicative scores at the same time. A wider, more accurate word range helps you everywhere:
- Speaking. In Describe Image and Re-tell Lecture you need precise words to report trends, structures and ideas quickly, without groping for the right term mid-sentence (which also hurts your fluency).
- Writing. Write Essay and Summarize Written Text reward range and accuracy of word choice. Repeating the same basic words, or using one slightly wrongly, both cost marks.
- Reading. Fill in the Blanks and Reading and Writing Fill in the Blanks are pure vocabulary and collocation tests: you pick the word that fits the meaning and the words around it.
- Listening. Highlight Correct Summary, Write from Dictation and Summarize Spoken Text all get easier when you instantly recognise academic words by sound and can spell them.
So vocabulary is never wasted study. One well-learned academic word can earn you marks in Speaking, Writing, Reading and Listening. The lists below are organised by where they pay off most.
1. Academic and lecture words
These general academic words appear constantly in PTE reading passages and lecture audio, and they make your own Write Essay and Re-tell Lecture answers sound more formal. Learn the meaning and one natural example for each.
| Word | Meaning / usage |
|---|---|
| analyse | to examine in detail. "The study analyses how income affects health." |
| significant | large enough to matter. "There was a significant rise in demand." |
| consequently | as a result. "Costs rose; consequently, prices increased." |
| establish | to set up or prove. "The research establishes a clear link." |
| factor | a thing that influences a result. "Cost is a key factor in the decision." |
| derive | to obtain from a source. "The data is derived from a national survey." |
| hypothesis | a proposed explanation to be tested. "The hypothesis was not supported." |
| phenomenon | an observed fact or event. "Migration is a global phenomenon." |
| subsequent | coming after. "Subsequent studies confirmed the finding." |
| predominantly | mainly, mostly. "The sample was predominantly young adults." |
| constitute | to make up or form. "Women constitute half of the workforce." |
| underlying | basic, beneath the surface. "The underlying cause is economic." |
2. Describe Image: trend and graph words
Describe Image gives you a graph, bar chart, map or process and 25 seconds to speak. You need ready-made language to report movement, comparison and proportion without hesitating. Keep a small bank of these and they will carry almost any chart.
| Word / phrase | Use it to say |
|---|---|
| rose / increased / climbed | a value went up. "Sales increased sharply in 2020." |
| fell / declined / dropped | a value went down. "Profits declined steadily after June." |
| peaked at | reached the highest point. "Demand peaked at 80 units in March." |
| plateaued / levelled off | stopped changing. "The figure plateaued in the final quarter." |
| fluctuated | moved up and down. "Temperatures fluctuated throughout the year." |
| roughly / approximately | give an estimate. "Roughly a third of users chose option A." |
| the highest / the lowest | name the extreme. "Country X recorded the highest value." |
| accounts for | state a share. "Transport accounts for 40 percent of the total." |
| in contrast / whereas | compare two things. "Imports grew, whereas exports fell." |
| overall trend | summarise the whole picture. "The overall trend is upward." |
A reliable structure: open with what the image shows, give the highest and lowest points, describe one clear trend, then close with the overall trend. The words above slot straight into that frame.
3. Linking and cohesion words
Linking words signal the relationship between your ideas. They lift your Written Discourse score in writing and make your spoken answers sound organised. Use them deliberately, but do not overload every sentence.
| To... | Use |
|---|---|
| add a point | moreover, furthermore, in addition, similarly |
| contrast | however, on the other hand, nevertheless, conversely |
| show cause | because, since, owing to, due to |
| show result | therefore, as a result, consequently, thus |
| give an example | for instance, for example, namely, such as |
| sequence ideas | firstly, subsequently, finally, ultimately |
| concede a point | although, even though, while, despite |
| conclude | in conclusion, to sum up, on balance, overall |
4. Formal synonyms (upgrade your common words)
Swapping a few everyday words for precise, formal ones is the fastest way to widen the range your Write Essay shows. Learn these pairs and reach for the right-hand column when you write.
| Common word | Stronger formal choice |
|---|---|
| big | substantial, considerable, significant |
| a lot of | numerous, a considerable number of |
| show | demonstrate, indicate, reveal |
| good | beneficial, valuable, favourable |
| bad | detrimental, adverse, harmful |
| get | obtain, acquire, gain |
| think | argue, contend, maintain |
| important | crucial, vital, essential |
| help | facilitate, assist, support |
| more and more | increasingly, a growing number of |
One caution: only use a word if you are sure of its meaning and grammar. The PTE scoring rewards accurate word choice, so a correct simple word always beats a misused fancy one.
5. Commonly mispronounced words for Read Aloud
In Read Aloud, your Pronunciation and Oral Fluency are scored from your voice. Certain academic words trip people up because the spelling does not match the sound, or the stress falls on an unexpected syllable. Practise saying these out loud (stressed syllable in capitals).
| Word | How to say it |
|---|---|
| comfortable | KUMF-tuh-buhl (three syllables, not four) |
| colleague | KOL-eeg (silent 'ue') |
| infrastructure | IN-fruh-struk-cher |
| environment | en-VY-run-ment (do not drop the 'n') |
| determine | di-TUR-min (ends 'min', not 'mine') |
| economy | i-KON-uh-mee |
| specific | spuh-SIF-ik (not 'pacific') |
| significant | sig-NIF-i-kunt |
| vegetable | VEJ-tuh-buhl (three syllables) |
| often | OF-en (the 't' is usually silent) |
| February | FEB-roo-air-ee |
| genuine | JEN-yoo-in (ends 'in', not 'ine') |
How to actually learn these words
- Learn words in chunks, not alone. Store "significant rise", "due to", "accounts for" as whole phrases. PTE rewards natural collocation, and chunks are easier to recall under time pressure.
- Say every word out loud. Because Speaking is scored acoustically, a word you cannot pronounce confidently is a liability in Read Aloud and Describe Image. Reading silently is not enough.
- Use a word three times. Write one sentence, say it aloud, then reuse it in a practice answer within the same week. Active use beats passive lists.
- Group by task. Keep your trend words for Describe Image and your linking words for essays in separate, short lists you can review in two minutes.
- Test under timing. The real proof is whether a word comes out smoothly in a timed answer. Run full, timed practice so recall becomes automatic.
