Choose Precise Meanings
Two words can be related without being interchangeable. Choose the word that preserves the intended meaning, strength and grammatical relationship.
Understand the pattern
Look at cost and price. A price is an amount charged; cost can refer to money spent or a wider sacrifice. The environmental cost of a journey does not mean the ticket price. A dictionary may group the words together, but the situation selects the useful sense.
Check direction and participants. Borrow describes receiving something temporarily; lend describes giving it temporarily. Raise normally takes an object: the company raised prices. Rise does not take that object: prices rose. Choosing a near-synonym often requires rebuilding the sentence, not replacing a single word.
Preserve strength. Helpful is not the same as essential; possible is not the same as certain. Replacing a modest claim with an impressive-sounding stronger word changes the message. In PTE preparation, accurate ordinary vocabulary is a better target than a sentence filled with unfamiliar words whose implications you cannot explain.
Language in context
| Word or pattern | Meaning or use | Example |
|---|---|---|
| borrow / lend | Receive / give temporarily | May I borrow your notes? I can lend you mine. |
| rise / raise | Go up / make something go up | Demand rose, so the supplier raised prices. |
| effective / efficient | Achieves the result / uses resources well | The method is effective but takes a lot of time. |
| economic / economical | Related to the economy / avoiding waste or excess cost | Economic conditions made an economical car attractive. |
Worked example
Reason through the choice
The new system saves time but still produces incorrect invoices. Is it necessarily effective at producing accurate invoices?
Answer: No. Time saving alone does not show that it achieves the required result.
The sentence gives evidence about speed and an unresolved accuracy problem. Calling the system fully effective would ignore the stated purpose. You can say it is faster while keeping the limitation explicit.
Try it yourself
Write your answers before opening the key. For open responses, the suggested answer is one possible version; keep the meaning and check the target pattern.
- Complete: Could you ___ me a pen? (borrow / lend)
- Correct: The temperature raised overnight.
- Does The change may help mean the same as The change will solve the problem? Explain.
Check answers and explanations
1. Lend. The listener would give the pen temporarily. Could I borrow a pen? reverses the grammatical perspective.
2. The temperature rose overnight. There is no object being raised. Rose is the past form of rise.
3. No. The second is more certain and promises a complete solution. Both certainty and the strength of the result have changed.
Use it in your PTE preparation
PTE Academic
When paraphrasing research, check the author's certainty and scope. A useful factor is not necessarily the main factor, and an association is not automatically a cause. Keep technical terms when a substitute would blur the claim.
PTE Core
Choose verbs that identify the action you need: replace a damaged item, repair it, or refund its price. These are different requests. A polite message still fails its purpose if the chosen verb asks for the wrong remedy.
Recall and transfer
Write one pair of sentences with rise and raise, then explain how their subjects differ. Add a near-synonym pair that you have confused before and record one context where switching the words would change the meaning.
