Weimplysomething by what we say. Weinfersomething from what somebody else says. The main difference between these two words is that aspeakercanimply, but a listener can onlyinfer.
When someone implies something, they put the suggestionintothe message:
Are youimplyingthat the team cheated?
When someone infers something, they take the suggestionout ofthe message. In order to underline this difference,inferis used with the prepositionfrom:
Then I think we mustinfer fromwhat they said that they believe we should reapply for the job.
Typical error
We don’t useinferto refer to what someone has said:
Are youimplyingthat I cheated?
Not:Are you inferring that I cheated?
