TOEIC Link Part 5: temper versus tamper
Temper and tamper are separated by one vowel, and both turn up in business writing, yet they describe opposite kinds of action. Temper is a verb meaning to moderate, soften, or make something less extreme (and a noun meaning a state of mind or the hardness of metal). Tamper is a verb, almost always used with with, meaning to interfere with or alter something improperly. Part 5 drops one into a sentence about adjusting or meddling with something, so it checks whether the blank means soften or interfere.

The core rule: moderate versus meddle
- temper = to moderate or soften something so it is less extreme (verb). She tempered her criticism with a few words of praise. / The board tempered its growth targets after the downturn. It answers how was it made milder? Link temper to moderate and soften: to temper is to bring something to a more reasonable level.
- tamper = to interfere with something improperly, usually followed by with (verb). Someone had tampered with the evidence. / The seal shows whether anyone has tampered with the package. It answers what was meddled with? Link tamper to meddle and interfere: to tamper with is to alter something you should leave alone.
The vowel carries the hook: temper with an e shares its root with temperate and temperature, both about keeping things moderate, while tamper with an a goes with unwanted meddling. If the blank means making something milder, it is temper; if it means interfering improperly, it is tamper (with).
Why Part 5 likes this pair
Because the two verbs differ by one letter, only meaning and grammar separate them. If the blank describes softening or moderating something, you need temper. If the blank describes interfering with something improperly — and is followed by with — you need tamper.
The manager __ the bad news with a clear plan for recovery.
A word meaning softened needs tempered.
The audit found that no one had __ with the financial records.
A word meaning interfered improperly needs tampered.
Spotting the clue
Decide whether the blank is a soften word or a meddle word:
- Does the blank describe making something less extreme? → choose temper (temper the criticism, temper expectations, temper enthusiasm with caution).
- Is the blank followed by with and about improper interference? → choose tamper (tamper with the lock, tamper with the results, tamper-proof seal).
A quick test: can you replace the blank with moderate or soften, as in moderated her criticism? Then it is temper. Can you replace it with meddle with or interfere with, as in meddled with the records? Then it is tamper. The grammar is a strong tell: tamper almost always takes with (tamper with something), while temper takes a direct object (temper something). Because both are action verbs that trip up test-takers, this pair sits alongside the other traps in the sound-alike verb pairs study guide.
Common Part 5 patterns
- Anything about softening or moderating wants temper: temper the remarks, temper optimism, temper the response, tempered with caution.
- Anything about improper interference wants tamper: tamper with the device, tamper with the vote, tamper-evident packaging, do not tamper.
- Grammar cue: a direct object and a sense of softening leans temper; the word with and a sense of meddling leans tamper.
If the blank means make milder, choose temper. If it means interfere with improperly, choose tamper.
Quick recap
- Temper = to moderate or soften something (verb) — you temper harsh news with a plan.
- Tamper = to interfere with something improperly, usually with (verb) — you must not tamper with the records.
- Part 5 test: swap in moderate → temper; swap in meddle with → tamper.
