CELPIP Speaking Task 5 Vocabulary for Comparing and Persuading

“Option A is cheaper. Option B is bigger. Option A is blue. Option B is near the station. I choose A.”

The speaker has compared features, but has not shown which criteria matter or persuaded a listener that the chosen option fits their needs.

CELPIP Speaking Task 5 is officially named Comparing and Persuading. The current official 2026 study pack shows two parts: 60 seconds in Part 1 to examine options and make a choice, then 60 seconds to prepare in Part 2 and 60 seconds to speak. The official strategy material tells test takers to compare options, choose one, review a new option, and explain why their choice is better while addressing the other person.

That interaction creates three different lexical moves: describe differences, judge trade-offs, and persuade a particular listener. This guide focuses on constraint, feasible, trade-off, outweigh, compelling, and resonate. Use the CELPIP vocabulary practice hub for activation and the Exam English hub for the wider exam collection.

The decision path

This is not a fixed speech template. The prompt and the new option determine which moves deserve time.

1. Convert features into criteria

A feature belongs to an option: $70, two bedrooms, five kilometres away. A criterion is the dimension you use to judge it: cost, capacity, location.

Instead of reading every label aloud, group the information:

“The first option is stronger on price, whereas the second is stronger on space and location.”

Useful comparison frames include:

• X is cheaper/more spacious/closer than Y;
• whereas between two complete contrasting clauses;
• both options offer X, but only Y provides Z;
• compared with X, Y would require...;
• X is better suited to someone who needs....

The listener does not need an inventory. They need a decision based on relevant dimensions.

2. Work within constraints

A constraint is a restriction or condition that keeps choices within bounds.

“Your main constraint is the $100 monthly budget, so the premium plan is not realistic unless you remove another expense.”

Natural forms include budget constraint, time constraints, work within a constraint, and constraints on travel. Constraint and limitation overlap; do not pretend they are rigid opposites.

A criterion helps rank alternatives. A constraint may rule an option out or set a boundary it must meet. If the listener must seat six people, a four-seat table fails a capacity constraint even if it looks attractive.

Do not invent constraints. If the prompt says the listener values convenience, use that. If it says nothing about colour preference, do not claim blue is essential.

3. Decide what is feasible

Feasible means capable of being carried out in practice under the stated conditions.

“Installing the ceiling fan is feasible only if the landlord permits permanent changes.”

Feasible does not mean desirable, attractive, affordable in every case, or certain to succeed. It answers can this realistically be done? A portable fan may be feasible but too weak for the room. A powerful system may be desirable but impossible within the budget.

Useful patterns:

• a feasible option/solution;
• financially feasible;
• feasible within the time available;
• not feasible unless....

This word becomes persuasive when you name the condition. Option A is feasible alone is less informative than Option A is feasible within your budget and does not require installation.

4. Name the trade-off honestly

A trade-off is a situation in which gaining one advantage requires accepting a disadvantage.

“The main trade-off is cost versus convenience: the downtown apartment is $250 more each month, but it would remove your one-hour commute.”

Natural patterns include a trade-off between X and Y, the trade-off is X for Y, and accept a trade-off. A simple difference is not automatically a trade-off. If one product is cheaper and better on every relevant dimension, there may be no sacrifice.

Stating a trade-off can strengthen persuasion because it shows that you have not ignored the alternative's advantage. Avoid pretending your choice is perfect.

When the consequence is uncertain, call it plausible only if the supplied facts make it reasonably possible. A shorter commute makes lower travel time plausible; it does not guarantee lower total expense. This distinction keeps a persuasive claim from becoming an invented fact.

5. Use “outweigh” to make the judgment

If one consideration outweighs another, it has greater importance or effect in the decision.

“For a family that travels every weekday, the time saved would outweigh the higher rent.”

The grammar is X outweighs Y, not X outweighs than Y or X is outweighing Y in this general evaluative use. The comparison does not erase Y. The rent remains a disadvantage; the speaker judges another benefit more important.

Give the listener-centred reason after the judgment:

“The portable fan is less powerful, but its flexibility outweighs that limitation for you because you need to move it between two rooms.”

Avoid unsupported scale. The benefits definitely outweigh all costs is too broad if the prompt provides only one small benefit.

6. Make a compelling case, not a loud one

Compelling can describe a reason, case, argument, story, or piece of evidence that strongly attracts attention or persuades.

“The most compelling reason is that this option meets the capacity requirement without exceeding the budget.”

Compelling does not mean true, proven, or emotionally dramatic. An argument may sound compelling and still require evidence. In Task 5, the best use names the exact reason, not merely Option A is compelling.

Natural combinations include compelling reason, compelling case, compelling evidence, and compelling argument. Do not use it as a universal replacement for good: a compelling price may be possible in advertising, but an affordable price or a strong price advantage is clearer in a comparison.

7. Build reasons that resonate with the listener

An idea resonates with someone when it connects strongly with their feelings, values, or experience.

“The community-centre option may resonate with you because you said staying connected to the neighbourhood matters after your move.”

The prompt must provide that deeper value or lived experience. Do not fabricate a personal value and claim it resonates. For an ordinary practical priority, communicate the fit more directly: This meets your need for a quiet workspace.

Use listener language:

• because you mentioned...;
• for your daily routine...;
• this would allow you to...;
• the feature that matters most for you is....

Persuasion is not pressure. It aligns a recommendation with the other person's stated needs.

Comparison is not yet persuasion

Compare these passages:

Description only

“The first gym costs $40 and closes at eight. The second costs $60 and stays open until midnight.”

Persuasion

“Although the second gym costs $20 more, I think it fits your schedule better. You finish work at nine, so the cheaper gym would be closed whenever you are available. For you, reliable access outweighs the monthly saving.”

The second passage selects a criterion, acknowledges a disadvantage, and ties the judgment to the listener.

Use concession without weakening the choice

A concession recognizes a genuine point on the other side:

• I agree that X is cheaper, but...
• Although Y offers more space, ...
• That is a real advantage; however, ...
• X would suit someone who..., whereas you need...

Do not invent a trivial concession merely to use although. The alternative's strongest relevant benefit is the useful one to acknowledge.

Then return clearly to your recommendation. A response that ends after praising the rival option may leave the listener unsure which choice you support.

A worked Task 5 response

Imagine that you chose a small community hall for a birthday gathering. It costs $180, seats 35 people, includes tables and chairs, and is near a bus route. The new option is a larger event space costing $320, seating 70, with parking but no included furniture. Your friend prefers the larger room.

“I understand why the larger event space appeals to you, especially because it has more parking. However, I still think the community hall is better suited to our gathering. We are expecting only about thirty guests, so capacity is not a constraint, and the smaller hall already includes the tables and chairs we need. The larger venue would cost $140 more before we even rent furniture. Its extra space is useful, but we would be paying for capacity we do not expect to use. The community hall is also near a bus route, which matters because several guests do not drive. For this group, convenient public transport and the included equipment outweigh the parking advantage. The most compelling reason is that the hall meets every confirmed requirement while leaving more of the budget for food. Unless the guest list grows substantially, I recommend that we keep the community hall.”

The response compares on capacity, total cost, equipment, parking, and transport. It concedes a real advantage, applies the listener's context, and states a condition that could change the recommendation.

Common vocabulary mistakes

• Feature dumping: group features under criteria and explain relevance.
• Constraint equals preference: a hard boundary and a nice-to-have are not the same.
• Feasible equals best: practicality does not settle the whole choice.
• Every difference is a trade-off: identify the gain and sacrifice.
• Outweighs than: use X outweighs Y.
• Compelling as proof: a persuasive reason is not automatically factual proof.
• Resonates without evidence: connect only to a listener need supplied by the prompt.
• Concession without return: acknowledge the alternative, then make your judgment.
• Universal superlatives: best for everyone is rarely supported; say better suited to your situation.

A Part 1 and Part 2 note grid

During Part 1, reduce each option to the same criteria:

Choose based on two or three important dimensions, not an emotional attachment to the first attractive feature.

When Part 2 introduces the other person's option, note:

1. its strongest advantage;
2. your concession;
3. the listener's decisive need;
4. one reason your choice still fits better;
5. one condition that could change your view.

This plan creates a responsive argument rather than a memorized comparison speech.

Quick check

1. Which sentence expresses a trade-off?

A. “Both chairs are made of wood.” B. “The folding chair saves space but provides less back support.” C. “The chair is beside the table.”

2. Which use of outweigh is grammatical and calibrated?

A. “For a daily commuter, the shorter journey may outweigh the higher rent.” B. “The shorter journey outweighs than rent.” C. “The benefit outweighs every possible cost for everyone.”

3. What makes a reason listener-centred?

A. It uses the longest word available. B. It connects the option to a need or constraint given for that listener. C. It describes every feature in the picture.

Answers: 1-B, 2-A, 3-B. A trade-off pairs a gain with a sacrifice. Outweigh takes a direct object. Persuasion depends on the listener's actual situation.

Practice prompt

Compare two ways for a friend to commute: a cheaper bus pass requiring two transfers, and a more expensive direct train pass. The friend works rotating shifts and sometimes finishes late.

Prepare for 60 seconds, then record a 60-second persuasion. Include:

• two shared criteria;
• one constraint;
• the central trade-off;
• a genuine concession;
• one outweigh judgment;
• a recommendation linked to the friend's schedule.

On replay, delete any feature that never becomes a reason. Check that your recommendation could change if the listener's constraint changed.
