Quick answer: The speaker IMPLIES (suggests without stating directly). The listener INFERS (draws a conclusion from what was said). Think: “I → Imply = send the message; You → Infer = receive it.”
Comparison Table
| Word | Meaning | Part of Speech | Example |
|---|
| imply | to suggest something indirectly without saying it outright | verb | Are you implying that I made a mistake? |
| infer | to draw a conclusion from evidence or indirect hints | verb | I inferred from her silence that she disagreed. |
Using Imply
Imply describes what a speaker or writer does. When you imply something, you hint at it or suggest it without explicitly saying so. The implication is built into what you say, how you say it, or what you leave unsaid. The verb imply follows a regular conjugation: implies, implied, implying.
Her raised eyebrow implied she did not believe him.
Are you implying that I wasn’t working hard enough?
The report implies that further investment is needed.
His tone implied frustration, even though he kept smiling.
Notice that in every case above, it is the person communicating — the one producing the message — who is doing the implying. The subject of imply is always the source of the communication (a person, a tone, a report, a silence).
Common Patterns with Imply
- imply that + clause — The data implies that costs will rise.
- What are you implying? — a common challenge to an indirect accusation
- by implication — The rule bans smoking and, by implication, vaping too.
- heavily / strongly imply — The ending strongly implies a sequel.
Using Infer
Infer describes what a listener, reader, or observer does. When you infer something, you reason your way to a conclusion based on clues, evidence, or implications. Inference is an active mental process — you are interpreting signals rather than being told something directly. The verb infer is also regular: infers, inferred, inferring.
From the evidence, the jury inferred that the defendant was present.
I inferred from his long silence that he was uncomfortable.
What can we infer from these statistics?
She inferred that the meeting had gone badly from the boss’s expression.
In every case above, a receiver of information — someone reading, listening, or observing — is doing the inferring. The subject of infer is always the person (or group) interpreting the message.
Common Patterns with Infer
- infer from + noun — I inferred from the email that she was unhappy.
- infer that + clause — We can infer that costs will increase.
- draw an inference — You should not draw inferences from limited data.
- by inference — By inference, the earlier policy also failed.
Memory Trick
The most reliable mnemonic is the speaker / listener rule:
- Imply → Issue a hint (the speaker sends it out)
- Infer → Interpret a hint (the listener takes it in)
Another way to remember: imply contains the letter sequence -ply, like supply — you are supplying a hidden message. Infer ends in -fer, like refer or transfer — you are transferring meaning from words into your own understanding. Or simply picture a conversation: the speaker “implies out”; the listener “infers in.”
Common Mistakes
Mistake 1 — Using infer when the subject is the speaker
✗ Are you inferring that I lied?
✓ Are you implying that I lied?
You cannot infer a question at someone — you imply it. The speaker implies; the listener infers.
Mistake 2 — Using imply when the subject is the listener or reader
✗ From the data, we can imply that demand is falling.
✓ From the data, we can infer that demand is falling.
The data does the implying; we (the readers/analysts) do the inferring.
Mistake 3 — Treating imply and infer as interchangeable synonyms
✗ The manager inferred that budget cuts were coming. (when the manager said something hinting at it)
✓ The manager implied that budget cuts were coming.
Ask: who is producing the message? That person implies. Who is receiving and interpreting it? That person infers.
Mistake 4 — Forgetting that non-human subjects can imply
✗ This evidence infers guilt.
✓ This evidence implies guilt.
Evidence, tone, data, and silence can all imply something. Only a conscious mind can infer.

Frequently Asked Questions
What is the difference between imply and infer?
Imply and infer describe two sides of the same indirect communication. The speaker or writer implies — they suggest something without stating it explicitly. The listener or reader infers — they draw a conclusion from what was said or written. Example: "Are you implying I was wrong?" (the speaker is sending a hint) vs "I inferred from her tone that she was unhappy" (the listener is interpreting a hint). The roles never swap: only sources imply; only receivers infer.
Is it correct to say "are you inferring that I lied?"
No — this is one of the most common errors with this pair. If you want to challenge someone who is hinting at something, the correct sentence is "Are you implying that I lied?" because the other person is the speaker who is sending the hint. "Are you inferring that I lied?" would mean you are asking whether they are drawing a conclusion that you lied, which is a different (and much rarer) situation. In everyday challenges and arguments, the correct verb is almost always "imply."
Can a report or piece of data imply something?
Yes. Non-human subjects such as reports, data, evidence, silence, tone, and body language can all "imply" something because they function as sources of communication. For example: "The figures imply that sales are declining" or "Her silence implied consent." Only a conscious mind can infer. So while a report implies, a reader infers from it. This asymmetry is a reliable test: if the subject is a person reading or observing, use infer; if the subject is the thing being read or observed, use imply.
What is the noun form of imply and infer?
The noun from imply is "implication" — meaning a suggestion or consequence that is hinted at rather than stated. Example: "The implication of her comment was that he had failed." The noun from infer is "inference" — meaning a conclusion reached by reasoning from evidence. Example: "The inference drawn from the data was clear." Both nouns are common in academic, legal, and formal writing. Note: "implication" also means a consequence or result in other contexts ("the implications of this decision"), which is a separate but related use.
How do I use "by implication" and "by inference" correctly?
"By implication" means something is suggested or entailed without being stated: "The new law bans all vaping devices and, by implication, their accessories too." "By inference" means something is understood through reasoning: "The policy was never written down, but by inference it was clear that complaints were discouraged." Both phrases are used in formal and academic writing. A quick test: "by implication" points to something hinted at by the source; "by inference" points to a conclusion reached by the reader or observer.
Is "infer" ever used incorrectly to mean "imply" in native speech?
Yes, unfortunately. In informal British and American speech, some native speakers do use "infer" where careful writers would use "imply" — for example, "Are you inferring I'm stupid?" This usage is considered non-standard and is widely criticised in style guides such as Fowler's Modern English Usage and Garner's Modern English Usage. In academic writing, professional communication, and formal exams (IELTS, CAE, CPE), you should always observe the distinction: speakers imply, listeners infer.
What is the past tense of imply and infer?
Both verbs are regular. The past tense of "imply" is "implied": "She implied that I hadn't tried hard enough." Note the spelling change: -y changes to -ie before -d. The past tense of "infer" is "inferred": "I inferred from his email that he was angry." Note the double -r before -ed, because "infer" ends in a single vowel + consonant. The present participles are "implying" and "inferring." These are common spelling pitfalls: infer → inferred/inferring (double r), imply → implied/implying (y → i before -ed).
Can the same sentence use both imply and infer?
Yes, and doing so can make the distinction very clear. For example: "She implied that the project was behind schedule, and I inferred that she was blaming me." Here, "she" is the speaker doing the implying; "I" is the listener doing the inferring. Another example: "The data implies a correlation, from which we can infer that the intervention worked." Writing both words in the same sentence is a useful exercise for learners because it forces you to assign each role correctly.
How is "imply" different from "suggest"?
"Imply" and "suggest" overlap but are not identical. "Suggest" can be direct ("I suggest we leave early") or indirect ("Her tone suggested anger"). "Imply" is almost always indirect — it specifically refers to hinting at something without stating it. You cannot say "I imply we leave early" as a direct recommendation; you would say "I suggest." However, "The evidence implies foul play" and "The evidence suggests foul play" are both natural and nearly synonymous. The key difference: imply stresses indirectness and hidden meaning; suggest is broader and can include direct proposals.
Do imply and infer appear on English language exams?
Yes. This pair is a classic test item at B2–C1 level (IELTS, Cambridge FCE/CAE/CPE, TOEFL). Exam tasks often ask you to choose the correct verb in a gap-fill or identify the error in a sentence. The most tested scenario is "Are you implying...?" vs "Are you inferring...?" — which tests whether you know that the person addressed is the speaker (implying), not the listener. Academic reading tasks also test whether students understand "infer from the passage" as a reading comprehension instruction, meaning: draw a conclusion from the text.
