The TOEFL iBT changed in January 2026. Advice built around retired task names can now send your vocabulary practice in the wrong direction. The current test includes Reading tasks such as Complete the Words and Read an Academic Passage, Writing tasks such as Build a Sentence, Write an Email, and Write for an Academic Discussion, and Speaking tasks called Listen and Repeat and Take an Interview.
Across those tasks, vocabulary mistakes are rarely solved by memorizing more difficult words. You need a repair process that checks the word's meaning, partners, form, grammar, and claim strength.
This lesson uses six repository-backed patterns:
| Expression | Useful pattern | Frequent repair |
|---|---|---|
| hinge on | outcome hinges on condition | restore on and dependency direction |
| feasible | feasible within + constraint | do not turn “doable” into “approved” |
| underscore | evidence underscores + point | do not turn emphasis into proof |
| account for | factor may account for result | keep for and limit causal strength |
| synthesize | synthesize material from sources | combine; do not merely list |
| imply | evidence implies that + clause | distinguish source from reader inference |
Use the TOEFL vocabulary practice hub and the broader Exam English hub as you work through the tasks.
A five-question repair workflow
When a sentence feels wrong, do not replace words at random. Ask:
- Choice: Does the word express the relationship I intend?
- Collocation: What words and prepositions naturally complete it?
- Form: Does the grammar require a noun, adjective, verb, or adverb?
- Complementation: What structure follows the word?
- Strength: Does the expression claim more than the evidence supports?
The same workflow applies differently in each task. Complete the Words makes letter shape and word class visible. Build a Sentence tests grammatical assembly. Write an Email adds purpose and audience. Academic Discussion and Take an Interview require accurate production under a communicative goal.
Mistake 1: correct meaning, broken collocation
"The success of the event hinges the weather." ✗
Hinge on means depend on or be contingent on something. The full pattern is outcome hinges on + condition:
"The success of the event hinges on the weather." ✓
The phrase also takes a gerund or a whether-clause:
"The decision hinges on receiving final approval." "The decision hinges on whether the venue is available."
It does not say the condition will be met. If the event hinges on the weather, the sentence establishes dependency, not a forecast.
For Build a Sentence, preserve the whole unit. A sequence containing whether / funding / available / hinges / the trip / is / on becomes:
"The trip hinges on whether funding is available."
Do not reverse the logic. Funding availability is the condition; the trip is the outcome that depends on it.
Mistake 2: a useful adjective acquires an invented meaning
"The dean approved the feasible proposal."
This may be true, but feasible does not tell you that approval happened. It means capable of being done or achieved in practice.
"The proposal is feasible within the available budget." ✓
Natural patterns include feasible within + time, budget, or constraint, a feasible approach, and technically feasible.
Do not treat feasible as a synonym for desirable, profitable, sustainable, or certain:
"Moving the seminar online is feasible, but the department has not decided whether it is desirable."
This distinction is useful in Write an Email. If a classmate proposes a new meeting time, you can say:
"A Friday meeting is feasible for me if we finish before 3 p.m."
The sentence gives a practical condition. It does not pretend to approve the plan for everyone.
Mistake 3: emphasis becomes evidence
"The attendance figures underscore that the new format caused the improvement." ✗
Underscore means emphasize or draw attention to. It does not itself prove, cause, or make something true.
"The attendance figures underscore the importance of making sessions accessible." ✓
Useful frames are underscore + noun phrase, underscore that + clause, and underscore the importance or need for + noun.
If the figures merely rose after a format change, avoid inserting causal certainty:
"The higher attendance underscores the potential value of the new format, although the figures alone do not establish why participation increased."
Do not confuse underscore with undermine. The first emphasizes; the second weakens or works against:
"The new evidence underscores the concern." "The contradictory record undermines the claim."
Mistake 4: causal language loses its object or calibration
"Longer opening hours may account the increase." ✗
Use account for + result:
"Longer opening hours may account for part of the increase." ✓
Account for can explain a fact or result by identifying relevant circumstances. It can also mean constitute a share: online orders account for 40% of sales.
The modal and part of matter. The phrase does not require a complete explanation:
"Differences in preparation may help account for the variation."
Do not confuse it with take into account, which means consider:
"The committee took travel time into account." "Travel time may account for some absences."
In Read an Academic Passage, the first sentence describes a decision process; the second offers a possible explanation. Keyword matching cannot replace the relationship.
Understanding is only the first step.
Lyra Practice helps you retrieve and use high-value workplace expressions in realistic situations until they feel natural.
Start a practice session →Mistake 5: synthesis becomes a list
"The student synthesized the two studies: Study A used interviews. Study B used a survey." ✗
Synthesize means combine material from separate sources or parts into a coherent whole. Listing two source summaries does not yet show how they connect.
"Synthesizing the two studies suggests that access depends on both service design and users' practical constraints." ✓
Useful patterns include synthesize findings, synthesize A and B, synthesize evidence from several sources, and synthesize material into a recommendation.
Synthesis need not create a completely novel theory or resolve every conflict. It must do more than copy or place separate statements next to each other.
In an Academic Discussion response, suppose one student emphasizes convenience and another emphasizes quality. A synthesis could be:
"The two comments can be synthesized into a broader criterion: the service should be easy to access without reducing the quality of support."
That sentence combines the contributions around one relationship.
Mistake 6: imply and infer change roles
In careful edited English, a statement, speaker, fact, or body of evidence implies something; a reader or analyst infers a conclusion from it.
"From the notice, students can imply that the room has changed." ✗
"The notice implies that the room has changed." "Students can infer from the notice that the room has changed."
Use imply that + clause, seem to imply, or evidence implies + noun/clause. The verb means suggest or indicate without direct statement, or carry something as a consequence. It does not mean prove.
The receiver-side conclusion can still be uncertain:
"We can reasonably infer from the repeated cancellations that the schedule is unstable, but we cannot infer the cause."
This distinction matters in Read in Daily Life and academic passages, where the task may ask about implied meaning. Track who supplies the signal and who draws the conclusion.
Complete the Words: coordinate letters, form, and meaning
Suppose a short passage reads:
The plan appears fea____ within the current budget, but its success will hi___ on whether trained staff are available.
The first slot needs an adjective after appears: feasible. The visible letters and budget constraint support it. The second needs the base verb after will and the complete pattern hinge on.
Do not solve either gap from topic alone. Your check is:
- visible letters;
- word class;
- sentence grammar;
- collocation;
- passage meaning.
No preparation list can predict every word. The transferable skill is coordinating these constraints.
Build a Sentence: preserve complete lexical units
Fragments:
may / the difference / account for / in participation / travel time
Correct assembly:
"Travel time may account for the difference in participation."
The modal takes the base form account, and the object follows for. A malformed version such as the difference may account travel time breaks both the collocation and the causal direction.
Fragments:
that / the survey results / underscore / clearer instructions / are needed
Correct assembly:
"The survey results underscore that clearer instructions are needed."
The evidence emphasizes the need. The sentence does not claim the survey alone proves a single solution.
Write an Email: choose purpose before vocabulary
Situation: A project partner suggests meeting daily, but you have another class at that time.
Weak response:
"Your plan is not feasible and it undermines everything."
The language is stronger than the facts and gives no route forward.
Controlled response:
"Meeting every day is not feasible within my current schedule because I have a class at that time. Could we meet on Tuesday and Friday instead? The success of the project will hinge on having enough shared time, so I am also available for short online check-ins."
Feasible connects to the actual constraint. Hinge on states a dependency without predicting failure. The requested alternative is explicit.
Academic Discussion: calibrate the argument
Source idea: Universities should replace lectures with online materials because attendance rose in one pilot.
Overstated response:
"The pilot underscores that online learning is proven superior."
Repair:
"The pilot's higher attendance underscores the value of flexible access, but it does not imply that online materials are superior for every subject. Course design and student support may also account for the result."
The revision separates emphasis, implication, and causal explanation.
Take an Interview: accuracy under personal examples
Question theme: Describe a group project that went well.
"Our progress hinged on having clear roles. At first, we had several separate ideas, so I synthesized them into one outline. That made the plan feasible within the time available because each person could work on a defined section."
The answer uses academic-capable language in a natural personal explanation. None of the expressions is inserted without a role.
Controlled repair set
1. Collocation
Before: The result hinges whether participants attend. After: The result hinges on whether participants attend.
2. Entailment
Before: The method is feasible, so the committee approved it. After: The method is feasible within the budget, although approval is still pending.
3. Strength
Before: The figures underscore proof that cost caused the decline. After: The figures underscore the need to investigate whether cost contributed to the decline.
4. Preposition and scope
Before: Weather accounts the entire change. After: Weather may account for part of the change.
5. Synthesis
Before: I synthesized the articles by listing their titles. After: I synthesized the articles by combining their findings into one explanation of the trend.
6. Source and receiver
Before: The reader implies from the email that the meeting moved. After: The reader infers from the email that the meeting moved.
Your final TOEFL vocabulary check
For every ambitious expression, mark:
- its complete collocation;
- the grammatical form required in this slot;
- the direction of the relationship;
- what the expression does not claim;
- whether it fits the task's audience and purpose.
Then replace any expression you cannot control with accurate plain English. That is a repair, not a retreat.
