Infer vs. Imply: Usage Guide

The use of infer to mean "suggest, hint" is commonly identified as an error for imply, especially when used with a human subject. Sentences like "They infer that it can't be done" and "Are you inferring that I'm at fault?" are, by this thinking, correctly rendered as "They imply that it can't be done" and "Are you implying that I am at fault?" In truth, the meanings of infer and imply have overlapped since the 16th century, making the need for a distinction a matter of preference. Those who wish to honor the distinction will limit their use of infer to its meanings relating to reaching conclusions and surmising or guessing, as in "Based on these facts we can infer certain conclusions"; they will avoid even the "to involve as a normal outcome of thought" and "point out, indicate" meanings.
