Definition:
A symbol is literary device that contains several layers of meaning, often concealed at first sight, and is representative of several other aspects, concepts or traits than those that are visible in the literal translation alone. Symbol is using an object or action that means something more than its literal meaning.
Example:
The phrase “a new dawn” does not talk only about the actual beginning of a new day but also signifies a new start, a fresh chance to begin and the end of a previous tiring time.
