Etymology

Origin of reinforcement

First recorded in 1600–10; reinforce + -ment

Explanation

Reinforcement is a way to learn and remember things, like a student who repeats the facts he has studied for a test over and over, or the ways we praise children when they share their toys or say "please" and "thank you" — reinforcement of the good manners we want them to use. You’ll often hear the word reinforcement used in relation to a building or other structure that gets additional mechanical support, but the word can be used in a broader sense as well. In addition to strengthening walls, reinforcement can refer to the strengthening or propping up of an argument or a particular point of view. For example, if you show up in class every day and ask questions, that adds reinforcement to the notion that you’re a diligent student.
