Usage Note

Infer has been used to mean “to hint or suggest” since the 16th century by speakers and writers of unquestioned ability and eminence: The next speaker criticized the proposal, inferring that it was made solely to embarrass the government. Despite its long history, many usage guides condemn the use, maintaining that the proper word for the intended sense is imply and that to use infer is to lose a valuable distinction between the two words. Although the claimed distinction has probably existed chiefly in the pronouncements of usage guides, and although the use of infer to mean “to suggest” usually produces no ambiguity, the distinction too has a long history and is widely observed by many speakers and writers.

Usage

The use of infer to mean imply is becoming more and more common in both speech and writing. There is nevertheless a useful distinction between the two which many people would be in favour of maintaining. To infer means `to deduce', and is used in the construction to infer something from something : I inferred from what she said that she had not been well . To imply (sense 1) means `to suggest, to insinuate' and is normally followed by a clause: are you implying that I was responsible for the mistake?

Infer vs. Imply

What's the difference between infer and imply?

Infer most commonly means to guess or use reasoning to come to a conclusion based on what has been suggested. To imply is to indicate or suggest something without actually stating it.

Infer and imply can be confused because they’re often used at opposite ends of the same situation. When someone implies something (suggests it without saying it explicitly), you have to infer their meaning (conclude what it is based on the hints that have been given).

For example, you might infer that your friend wants cake for their birthday because they keep talking about how much they like cake and reminding you that their birthday is coming up. Your friend didn’t actually ask for cake, but they implied that they want it by giving you hints. You used these hints to infer that they want cake.

Of course, there are situations in which you might infer something when nothing was implied or nothing was intended to be implied.

Probably due to the association between the two words, infer is sometimes used to mean the same thing as imply—to hint or suggest. Even though this can be confusing, the meaning of infer can usually be easily inferred from the context in which it’s used.

Here’s an example of infer and imply used correctly in a sentence.

Example: Even though he only implied that he may be in trouble, we correctly inferred that he was.
