Are "imply" and "infer" synonyms?
These two terms cannot be correctly used interchangeably. In fact, "imply" and "infer" are antonyms. If I say that your car is too small, I would imply that I don't want to ride in it. YOU would infer from my comment that I do not want to ride in it. The subject of "imply" is the source of an implication while the subject of "infer" is the recipient of an implication.
