The key idea
Choose hedging words that show how strongly your evidence supports each claim.
What is it for?
Learn to make claims that match the strength of your evidence.
What you need to know
- Use may, might and could when something is possible but not certain.
- Use seem, appear and tend to when evidence suggests a pattern.
- Use probably, arguably and to some extent to limit claims.
- Use clearly and undoubtedly only when strong evidence supports them.
- Avoid absolute words such as always, never and proves without enough evidence.
- Hedge important claims, but keep well-supported facts direct.
1. Why careful claims matter
A claim is a statement about something.
Your evidence should support the strength of that statement.
Without enough proof, a strong claim can sound careless.
Hedging shows what you know and what remains uncertain.
It also helps readers judge your ideas fairly.
- Strong claims need strong evidence.
- Careful claims leave room for other explanations.
- Use direct language for facts you can verify.
Social media destroys attention.
This claims a strong effect on everyone.
Heavy social media use may reduce attention.
May shows that the effect is possible, not certain.
2. Choose the right hedge
Different hedges show different levels of certainty.
May, might and could present possible results.
Seem and appear show what the evidence suggests.
Tend to describes a pattern that is not universal.
Qualifiers limit a claim to a smaller area.
- Use may, might or could for possible effects.
- Use seem or appear when the evidence gives an impression.
- Use tend to when a pattern has some support.
- Use probably when something is likely, but not certain.
- Use to some extent to show that a claim is partly true.
Short study breaks may improve concentration.
May presents a possible result.
The new app appears to help some learners.
Appears shows that the evidence suggests a result.
Students tend to remember information they practise.
Tend to describes a common pattern, not every student.
3. Match your words to your proof
Choose a hedge after checking the evidence.
A small test may suggest a result, but it cannot prove a general rule.
Several reliable studies may support a stronger claim.
Clearly and undoubtedly express high certainty.
Use them only when the available evidence justifies that certainty.
- One example rarely supports a claim about everyone.
- Use it is likely that when the evidence supports a probable result.
- Use arguably when a reasonable case supports an interpretation.
- Use clearly or undoubtedly only with strong evidence.
It is likely that regular practice improves recall.
Likely presents a result as probable.
Arguably, shorter lessons can improve attendance.
Arguably presents a reasonable view, not a proven fact.
The records clearly show a rise in attendance.
Clearly is suitable when reliable records support the statement.
4. Avoid weak or extreme writing
Too much hedging makes every sentence sound uncertain.
Keep direct statements when the facts are clear.
Words such as always and never leave little room for exceptions.
The word proves is too strong when evidence only suggests a result.
Replace absolute claims with narrower, better-supported statements.
- Do not put may before every verb.
- Keep dates, numbers and verified details direct.
- Replace always with often when the pattern has exceptions.
- Replace proves with suggests when the evidence is limited.
The survey suggests that reminders improve attendance.
Suggests matches evidence that points towards a result.
Online lessons often help students study at home.
Often allows for students who do not benefit.
The timetable starts at nine.
No hedge is needed for a verified timetable.
How to do it, step by step
- Write your main claim in one clear sentence.
- Check what evidence supports the claim.
- Choose a hedge that matches the evidence.
- Limit the claim if it covers too many people or situations.
- Remove extra hedges and keep verified facts direct.

UK / US: Hedging is used in both British and American English. Spelling may differ, as in analyse (UK) and analyze (US).
Level up: Replace basic words (good, very, nice) with stronger ones. See our A2 to C1 upgrades page.
Model text
Before and After: A More Careful Claim
Before: Overstated paragraph
Technology destroys students' ability to concentrate. Every learner checks a phone during lessons, and nobody remembers information after using a screen. Online tools always make homework easier, so schools must stop using them. A single classroom survey proves that digital learning harms every student. Clearly, printed books are the only reliable way to study. Teachers who use technology waste valuable lesson time, while students who work on paper always achieve better results. These statements sound certain, but the evidence does not support such wide claims.
The paragraph uses absolute words and makes claims about every learner.
After: Carefully hedged paragraph
Heavy phone use may reduce students' concentration during lessons. In one classroom survey, several learners reported checking their phones frequently. This finding suggests that phone habits can affect study time, but it does not establish the same effect for everyone. Online tools may also make some homework tasks easier, particularly when instructions are clear. To some extent, printed books can support focused reading because they offer fewer digital interruptions. However, the best choice probably depends on the task, the learner and the available support. It is likely that a balanced approach will suit many classrooms. Further evidence would help teachers decide which tools work best for different groups. Until then, schools could compare results from printed and digital tasks before changing their policies.
The revised paragraph limits its claims and links them to available evidence.
Common mistakes

Plan it, then check it
Plan
- Write the main claim without adding extra details.
- List the evidence that supports your claim.
- Choose a hedge that matches the evidence.
- Narrow the claim if it covers too many people or cases.
- Keep facts direct and remove unnecessary hedges.
Check
- Does each claim match the evidence?
- Have I avoided unsupported words such as always and proves?
- Have I chosen hedges with the right level of certainty?
- Have I kept verified facts direct?
- Have I removed repeated or conflicting hedges?
Practice
Choose the best hedged sentence
Choose the sentence that matches the limited evidence.
1.A survey of ten learners found better results after short breaks.
A small survey suggests a possible benefit, not a universal result.
2.One teacher says that an app saves time.
One teacher's experience cannot establish a general result.
3.Several class records show fewer missed lessons after reminders began.
The records support a possible link without proving every case.
4.A learner often remembers words after writing them down.
One learner's experience supports a possibility, not a universal rule.
5.A school trial found that some students finished digital tasks faster.
The trial suggests a benefit for some students, not everyone.
6.A timetable confirms that the library opens at nine.
A verified timetable supports a direct statement without hedging.
Turn strong claims into careful claims
Match each strong claim with its careful version.
1.Technology destroys concentration.
2.Every student learns faster with videos.
3.Phone reminders always improve attendance.
4.Printed notes are the only useful study tool.
5.One survey proves that online lessons work.
6.Digital exercises never cause problems.
Complete each careful claim
Write one suitable hedge or qualifier in each gap.
1.Short practice sessions improve memory.
May presents improved memory as a possible result.
2.The new study method appears save time.
Appears to introduces a possible result.
3.Learners tend remember words they practise.
Tend to describes a common pattern without covering everyone.
4.It is that clear instructions will reduce mistakes.
Likely presents the result as probable, not certain.
5., printed notes can support focused revision, but they do not suit every task.
Arguably introduces a reasonable view rather than a proven fact.
6.The survey that reminders may improve attendance.
Suggests matches evidence that points towards a possible result.
Correct one small mistake
Change only the word or words needed to correct each sentence.
1.Online lessons always helps every learner.
The original claim is too broad and has an incorrect verb form.
2.The survey prove that all students need videos.
Prove is too strong for a survey that cannot establish every case.
3.The app appears help students organise their notes.
Appears needs to before the next verb.
4.The new method might possibly save time.
Might and possibly express the same uncertainty.
5.The records clearly might show fewer missed lessons.
Clearly conflicts with the uncertainty expressed by might.
