Here's why:
* Literal Meaning: Literally, "go make a living" would mean to physically go somewhere and create a living thing. This doesn't make sense in everyday language.
* Figurative Meaning: It means to earn money or support oneself financially.
* Metaphor: A metaphor is a figure of speech where something is described as something else, creating a comparison. "Go make a living" doesn't directly compare one thing to another.
Examples of metaphors:
* "Life is a journey." (comparing life to a journey)
* "He's a lion in the boardroom." (comparing a person to a lion)
Therefore, while "go make a living" is figurative in meaning, it's not a metaphor.
