Vocabulary precision: meaning, patterns and evidence
A longer word can make a sentence less accurate
- Compare “Students got advice on their drafts” with “Students achieved evidences on their drafts.” The second sentence sounds ambitious but changes the meaning and misuses the nouns. Choose vocabulary that does a clear job before choosing vocabulary that looks impressive.
- This lesson practises four decisions: meaning, word partners, sentence pattern and evidence. Its short checks do not assess a complete essay or predict a band. A word wearing a top hat still needs to say the right thing.
Which change most improves vocabulary use?
Meaning and appropriate use matter. A longer word can make the sentence inaccurate.
Passing these short checks proves an official Writing band.
The checks concern taught distinctions. They do not assess a complete response or predict a band.
Learn the word with its useful partners
- A collocation is a familiar combination of words. Useful patterns include give feedback on a draft, meet a deadline, participate in a discussion and provide access to a service. Learn a whole usable pattern, not only an isolated translation.
- The pattern carries meaning. Attendance concerns being present; participation concerns taking part. A register can show attendance without proving that every learner joined a discussion. A timetable can show when a class happens without describing its curriculum, the content taught.
Original situation: a tutor comments on a report. The learner rewrites its unclear introduction before Friday's deadline.
The tutor gave feedback on the report. The learner revised the introduction and met the deadline.
Here, revise means change the draft. In revise for an examination, it means study material again. The surrounding words help establish which meaning is intended.
Which sentence fits the tutor-and-report situation?
Give feedback on a report is a useful pattern for comments about the work.
A register records who was present. What does it directly record?
Presence establishes attendance; it does not establish participation or understanding.
Complete the taught pattern with ONE WORD: participate ___ a discussion.
The taught pattern is participate in a discussion.
In the sample, the learner revised the introduction. What does revised mean here?
The object is a piece of writing. The other taught sense appears in revise for an examination.
Put the right word form into the right pattern
- In the following ordinary uses, affect is a verb and effect is a noun: “A change may affect attendance” and “A change may have an effect on attendance.” Use affect something, not affect on something, in this pattern. These examples are possibilities, not findings from a study.
- Use some feedback, a piece of feedback, evidence or a piece of evidence in their ordinary uncountable uses. Do not repair three evidences by replacing it with another unfamiliar word; identify the intended countable unit, such as three observations.
A dictionary entry can contain several meanings and patterns. The word effect also has a verb use, but that does not make it interchangeable with affect in every sentence. Check the particular meaning and example pattern you need. Do not turn a useful common pattern into an “always” rule about every possible use.
Choose the usual verb pattern for a possible influence.
Affect is the verb in this use and takes attendance directly, without on.
Complete with ONE WORD: The change may have an ___ on attendance.
Have an effect on uses the noun effect. It is not the verb affect pattern.
Which sentence uses the ordinary noun pattern taught here?
Feedback is ordinarily uncountable in this meaning; some feedback is appropriate.
Because effect is a noun in have an effect on, it can never be a verb in any other context.
The lesson explicitly distinguishes a useful common pattern from an absolute rule about all meanings.
Name the quantity before describing the change
- Invented example: the share of commuters who walk rises from 20% to 30%. This is a rise of 10 percentage points. Relative to its starting share, the increase is 50%, because the change of 10 is half the initial 20. “Up by 10%” would describe a different change.
- Rise to names the final value; rise by names the change. “The share rose to 30%” is supported. “The share rose by 30 percentage points” is not. A proportion alone does not establish how many people are involved if the totals are unknown.
Write the number and unit first, then check every descriptive word against them. The share increased is a change in a proportion. The number increased is a change in a count. The figure remained stable requires evidence of little change over the stated period, not merely one measurement.
The share rises from 20% to 30%. What is its increase in percentage points?
Subtract the shares: 30 minus 20 is 10 percentage points.
Relative to the starting share of 20%, how large is the increase to 30%?
The change is 10; 10 divided by the starting 20 equals 0.5, or 50%. This differs from the percentage-point change.
Which sentence accurately names the final share?
To introduces the final value, 30%. By introduces the change, which is 10 percentage points here.
If the total number of commuters is unknown, the shares alone prove how many additional people walked.
Shares are proportions. Counts also require the relevant totals.
Keep the strength of the claim within the evidence
- Original notice: “Three participants said the room was convenient because it was near their workplace. The organiser recorded their comments but did not compare other rooms.” This supports a statement about those participants' comments. It does not prove that the room is convenient for everyone or the best available room.
- Convenient means suitable or easy for a particular purpose. Accessible concerns whether people can reach, obtain or use something. The words can describe related qualities, but they are not automatic replacements. A nearby room may still have a barrier that prevents someone using it.
Overstated: “The comments prove that the room is the best option for all residents.”
Supported: “Three participants described the room as convenient because it was near their workplace.”
The second sentence states who gave the opinion and why. It does not invent a comparison, a cause of improved performance or a population-wide conclusion.
What do the three participants’ comments establish?
The notice identifies three opinions and their reason. It does not provide the proposed comparisons or universal conclusion.
Convenient and accessible can always replace each other without changing meaning.
Convenient concerns suitability or ease for a purpose; accessible concerns the ability to reach, obtain or use something. The qualities can differ.
Make contrasts clear without changing their meaning
- “Attendance rose, whereas participation in discussion remained unchanged.” The sentence contrasts two stated measures. “Attendance rose because participation remained unchanged” adds a cause that the two measures do not establish.
- Keep the pattern complete: “Although attendance rose, discussion participation remained unchanged.” In this pattern, do not add but after the although-clause. A connector is a signpost, not permission to invent a relationship.
- Original short paragraph: “The workshop attracted more attendees in its second month. However, the discussion record showed no increase in the number who spoke. Higher attendance therefore did not establish greater discussion participation.” The paragraph uses a specific example and a limited conclusion; it does not claim that attending a workshop has no value.
Attendance rose and discussion participation stayed unchanged. Which connector expresses the stated contrast?
Whereas signals contrast. The data do not establish a cause or universal learning effect.
Choose the complete pattern taught in the lesson.
Although already introduces the contrast clause. The taught pattern does not add but, and the third option invents a different fact.
Use a word record, then transfer it to a new situation
- Keep a short word record: meaning → useful pattern → original example → contrast or trap. For feedback, record comments that help review work → feedback on a draft → The tutor gave feedback on my introduction → feedback is not the same as a final grade. Then close the record and make a different example.
- Transfer task: an invented notice says “Applications close on Thursday. Eligible applicants may book an interview if an appointment is available.” Write two clear sentences that distinguish the deadline, eligibility and availability. Explain why being eligible does not guarantee an appointment. Suggested response: “The application deadline is Thursday. An eligible applicant can book an interview only if an appointment is available, so eligibility alone does not guarantee a booking.”
- Return to one paragraph you wrote. Replace one vague word with a more precise word, repair one word pattern and remove one unsupported claim. Read it aloud to check that it still sounds natural. Your vocabulary does not need a costume change every sentence.

Match each word-record entry to its job.
The record connects a meaning with a usable pattern, a concrete sentence and a boundary on its use.
The notice allows eligible applicants to book if an appointment is available. Which statement is supported?
The booking still depends on availability, and the separate Thursday deadline remains a condition for applying.
