A symbol is something that represents something else. We know—super helpful, right?
Want more clarity? Okay, how about this: a symbol is a word, an image, or anything that somehow represents a larger idea. In other words, what you see is not just what you get. Symbols are more than meets the eye. They're loaded with meaning.
Example? In America, eagles are a symbol of freedom. In punk rock, the safety pin is a symbol of rebellion. In western literature, the apple is often a symbol for sin. See how that works?
But when talking about symbols, it's also important to remember that the symbol is still itself, in addition to what it symbolizes. So when you see an apple in a book, and immediately think of sin, don't forget that it's also just an apple. And someone's probably going to eat it. Or at least bake it into a pie.
