Symbolism Definition. Symbolism is the use of symbols to signify ideas and qualities by giving them symbolic meanings that are different from their literal sense. Symbolism can take different forms.Generally, it is an object representing another to give it an entirely different meaning that is much deeper and more significant. Sometimes, however, an action, an event or a word spoken by someone may have a symbolic value.ymbolism gives a writer freedom to add double levels of meanings to his work: a literal one that is self-evident and the symbolic one whose meaning is far more profound than the literal one. The symbolism, therefore, gives universality to the characters and the themes of a piece of literature.
