What do we call a word or phrase that signifies something else, functioning as a sign or mark?

A symbol is a word or phrase that represents or stands for something else, often conveying deeper meanings or associations beyond the literal interpretation. In literature and communication, symbols are used to connect concrete concepts with abstract ideas, allowing for richer expression and interpretation. For example, a dove may symbolize peace or a red rose may signify love.

In contrast, the other options refer to different literary devices. Allegory involves a narrative or story with a dual meaning, often moral or political, where characters and events symbolize larger ideas. Imagery pertains to descriptive language that appeals to the senses, helping readers visualize scenes or emotions. Allusion refers to an indirect reference to another text, person, or historical event, enriching the context with pre-existing meanings. While all of these terms involve layers of meaning, they do not fit the specific definition of a word or phrase that signifies something else in the same way that a symbol does.
