Origin of infer

First recorded in 1520–30; from Latin inferre, equivalent to in- + ferre “to bring, carry, bear”; see origin at in-2, bear1

usage note For infer

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.

word story For infer

The English verb infer has always been used in logic to mean “to conclude by reasoning or from evidence.” It comes from the Latin verb inferre “to carry in, enter, introduce, inflict,” composed of the prefix in- “in, into” and ferre “to carry, bear.” Inferre meaning “to conclude, draw an inference, infer” is very rare in Latin, occurring only in the writings of Cicero (106–43 b.c.), Roman statesman and man of letters, and the great, commonsensical Roman rhetorician Quintilian (who lived about a.d. 35–95).

usage For infer

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?
