Authors do not always tell readers everything they want them to know.
Good readers infer when they want to understand more than what the author has written.
Inferring occurs when you understand something that is not stated directly.
We infer when we try to read facial expression, body language, and tone of voice.
For example, if you saw a friend looking upset and holding his arm at recess, you might infer that he hurt himself on the playground.
We infer in many ways in our lives.
