The importance of contextual cues

Now, even if you did not know what fishmonger meant,you can use some contextual clues.One: Polonius reacted in a negative way, so it must be bad.Two: Fish smell bad, so it must be bad.And three: monger just doesn't sound like a good word.So from not even knowing the meaning,you're beginning to construct some characterization of the relationship between Hamlet and Polonius,which was not good.
