In a report or essay, you often don't want to sound 100% certain, because you can't be. Words like may, might, could, suggest, appear leave room for doubt. There's no single right wording. There's the one that fits how sure you really are.
Saying it carefully, not as a fact
Strong: This proves the method works.
Careful: This may suggest the method works.
Careful: The results appear to support it.
Not "The results prove it, in a piece of careful research." — say "The results may suggest it, in a piece of careful research.". When you can't be fully sure, the softer wording fits the kind of writing better.
The same finding can be stated as a hard fact or stated with room for doubt. Tap each one to hear what it signals.
This proves that sleep affects memory. — sounds 100% certain: too strong for most research, where you rarely prove something outright
This may indicate that sleep affects memory. — leaves room for doubt: fits careful writing, where you can't be fully sure
This seems to show that sleep affects memory. — careful and measured: signals a likely link, not a settled fact
may / might / could + base verb
The most common way to hedge is a modal: may, might, or could + the base verb. It turns a flat claim into a careful possibility. "Prices rise in winter" (certain) → "Prices may rise in winter" (careful). Keep the base verb after the modal — never add -s, -ed, or to.
Costs rise sharply. → Costs might rise sharply.
This explains the gap. → This could explain the gap.
The change improves results. → The change may improve results.
Not "This may explains the gap." — say "This may explain the gap.". After a modal, use the base verb (explain), not the -s form (explains).
Try it: Stress causes the illness. The blunt claim is "Stress causes the illness." You aren't fully sure, so soften it. Build the careful version. (Leave out the word you don't need.) Answer: Stress may cause the illness. — A modal softens the claim, and after may you use the base verb: Stress may cause the illness. "Causes" still sounds certain and breaks the modal pattern, so leave it out. It's may + the base verb.
Cautious verbs: seem, appear, tend to, suggest
A small set of verbs does the softening for you. seem to and appear to report how something looks, not what is settled. tend to says it's usually true, not always. suggest / indicate point toward an idea without claiming proof. Shape: subject + seem / appear / tend + to + base verb (results tend to fall), or subject + suggest / indicate + a that-idea (the data suggests that…).
The numbers appear to fall in winter.
Older users tend to prefer larger text.
The results suggest that the method helps.
Not "The data proves the plan works." — say "The data suggests the plan works.". Swap the certain verb (proves) for a cautious one (suggests) when the evidence isn't final.
Each line reports the same result with a different verb. Tap each one to hear how certain it sounds.
The data shows a clear link. — states it as a plain fact: strong, and fine only when you really are sure
The data suggests a link. — points toward it without claiming proof: a careful, common choice in reports
There appears to be a link. — keeps the most distance: signals what it looks like, not what is settled
Softening words: perhaps, somewhat, about
Small words dial a claim down without changing the sentence shape. perhaps / possibly mark something as not certain. somewhat / relatively / fairly shrink how strong a description is (somewhat higher, not just higher). about / around / roughly show a number is an estimate (about 40%, not 40%). Drop one in front of the word you want to soften.
The plan is better. → The plan is somewhat better.
Sales rose 40%. → Sales rose about 40%.
It works in cold weather. → It possibly works in cold weather.
Not "Sales rose exactly about 40%." — say "Sales rose about 40%.". About already means the number is an estimate, so drop exactly — the two contradict each other.
Try it: Your measurements ranged from 38% to 42%, so the figure isn't fixed. Cost fell by ___ 40%. (about / exactly / precisely) Answer: about — The figure is an estimate, so an approximator fits: about 40%. "Exactly" and "precisely" claim a fixed number you don't actually have. When a number is rough, mark it with about, around, or roughly.
Distancing frames: It could be argued that…
In academic writing you can step back from a claim with a ready-made frame, so it reads as one possible reading rather than your fixed opinion. Useful ones: It could be argued that…, It seems likely that…, This suggests that…, The evidence points to…. Put the frame first, then your claim as a normal that-idea. Keep that — it joins the frame to the claim.
The policy failed. → It could be argued that the policy failed.
Screen time harms sleep. → This suggests that screen time harms sleep.
The trend will continue. → It seems likely that the trend will continue.
Not "It could be argued the policy failed." — say "It could be argued that the policy failed.". Keep that after the frame — without it the frame doesn't join cleanly to your claim.
Try it: Rashid is writing the discussion section of an essay. His evidence is real but limited, and he doesn't want to overstate it. Which opening fits cautious academic writing? (It could be argued that early support improves outcomes. / It is obvious that early support improves outcomes.) Answer: It could be argued that early support improves outcomes. — The evidence is limited, so the distancing frame fits: It could be argued that… presents the claim as one reasonable reading. "It is obvious that" overstates limited evidence and dares the reader to disagree. In cautious writing, frame the claim rather than declaring it settled.
Leave room for exceptions
Blanket words like all, every, always, never are easy to disprove — one exception breaks the whole claim. Swap them for words that allow exceptions: many / most / some instead of all, often / usually / generally instead of always, tend to instead of a flat statement.
All teens use it. → Most teens use it.
It always works. → It usually works.
People never read the terms. → People rarely read the terms.
Not "Everyone always ignores the warning." — say "Most people usually ignore the warning.". Most / usually survive a counterexample; everyone / always collapse the moment you find one.
The same idea can cover everyone or leave room for exceptions. Tap each one to hear what it signals.
All students always prefer this. — no exceptions allowed: an easy claim to disprove with a single counterexample
Many students tend to prefer this. — leaves room for exceptions: a safer, more honest claim in writing
This is often true, though not always. — names the exceptions openly: careful and hard to argue against
