A symbol is something that represents something else. Symbols can take many forms including objects, pictures, written words, sounds, and numerals. Examples of common symbols include religious symbols, mathematical symbols, and political symbols like the maple leaf for Canada. Symbolism is used in writing to provide additional meaning beyond a literal description. For example, a storm could symbolize conflict or a transition from day to night could represent moving from goodness to evil. In literature, Lord of the Flies uses Ralph's conch shell to symbolize order versus Jack's savagery. Harry Potter also contains symbolism like snakes representing evil.
