Imply means to suggest something without saying it directly; infer means to work that meaning out from the evidence. They are two ends of the same message: the speaker or writer implies, and the listener or reader infers.
the source implies; the audience infers — a writer implies, a reader infers.
These two are confused so often that misusing them is almost a cliché — but they are not interchangeable, they are opposite ends of one act of communication. Imply comes from the Latin implicare, 'to fold in': the sender tucks a meaning into the words. Infer comes from inferre, 'to carry in': the receiver draws that meaning out. One gives the hint; the other takes it. If you are the source, you imply; if you are the audience, you infer.
imply
To imply is to carry a meaning without saying it outright — from the Latin implicare, 'to fold in', the sense tucked inside the words rather than laid on top of them. A tone can imply disapproval; a report can imply blame while naming no one. The meaning is really there, just left for the other side to pick up. This is the half of the pair people get wrong: the speaker or writer implies, while the listener or reader is the one who must infer what was meant.
infer
To infer is to reach a conclusion the evidence points to without its being stated outright — from the Latin inferre, 'to carry in'. You see wet streets and infer it rained; a reader infers a character's mood from a single gesture. Inference fills the gap between what is shown and what is meant, so it always carries some risk: a plausible inference can still be wrong. Crucially, the writer implies; the reader infers — the two are not interchangeable.

Picture one pin board twice. First, a hand runs red strings from the clues to a blank centre card and slips away — the threads point at an answer it never names: that is imply, and the one who imPLIES is PLanting the hint (the writer/speaker). Then a detective reads where every string converges and the blank lights up into the culprit's face: that is infer, and the one who INFers is INvestigating (the reader/listener). Source folds the meaning in → imply. Audience draws it out → infer. So a writer implies; a reader infers — never the other way round.

A simple rule settles almost every case: the source implies, the audience infers. Watch the common error 'the passage infers that…' — a passage can only imply; a person infers.
