ELI5: Explain Like I'm 5

Concept

A concept is an idea or thought. It's something that can exist in our minds, like a picture or an idea. People use concepts to help them understand and explain the world around them. For example, the concept of a house is a thought or mental picture of a building that provides shelter. People use concepts to organize their lives, plan for the future, and understand the world. Ideas like justice, freedom, and democracy are also examples of concepts.
