What clue might let you know that an author is using a figure of speech

One clue that might let you know that an author is using a figure of speech is when a sentence or phrase does not seem to be meant in its literal or dictionary meaning, and instead conveys a figurative or metaphorical meaning. Additionally, figures of speech often involve the use of vivid language, analogies, comparisons, or symbolic expressions that deviate from the usual way of stating something. Finally, figures of speech are intentionally used by authors to create emphasis, evoke emotions, or add depth and richness to the text.
