ELI5: Explain Like I'm 5

Symbol

A symbol is a picture or a sign that represents something else. It's like when you draw a heart to show someone you love them. The heart is a symbol for love. Symbols can also be letters or numbers, like the letter "A" and the number "1". Sometimes, symbols are used to represent things we can't see or touch, like feelings or ideas. For example, a smiley face can be a symbol for happiness or a peace symbol can be a symbol for unity. Symbols help us communicate and understand things without using a lot of words.
