There are two ways in which the word "infer" is sometimes used as if it meant "imply". "Implication" is done by a person when making a "statement", whereas "inference" is done to a proposition after it had already been made or assumed. Secondly, the word "infer" can sometimes be used to mean "allude" or "express" in a suggestive manner rather than as a direct "statement". Using the word "infer" in this sense is now generally considered incorrect.  
From Latin inferō.
