Here's why it can be a metaphor:
* Time as a physical entity: The phrase treats time as if it were a tangible thing, like a physical object you can hold or measure. We say "just a minute" as if we're handing someone a small amount of time, rather than acknowledging the abstract nature of time itself.
* Underestimating time: "Just a minute" often implies that the task will be very quick, even though it might take longer. This is a metaphorical exaggeration, as we often underestimate how long things will actually take.
Here's why it might not be a metaphor:
* Literal meaning: Sometimes "just a minute" is used literally, simply meaning a short period of time. There's no figurative language being used, just a simple statement of duration.
Ultimately, whether "just a minute" is a metaphor depends on the speaker's intention and the context of the conversation.
