quote:Some say summer is for recreation, But me? I prefer relaxation. In my hammock I snore And (to use metaphor) I’m not lazy. It’s just aestivation.
Tim had questioned whether this usage of aestivation (variant of estivation) could truly be called a "metaphor". I see his point. But is this figurative usage indeed a metaphor, and if not, what do you call it?
Metaphor: my laziness is me going underground for summer.
Figurative: I am literally going underground or somewhere you could almost call underground, for summer or a period you could almost call summer. (But not literally both underground and summer.)
I don't see it as a metaphor since you are saying that your relative inaction actually is aestivation. A metaphor is like "My brother is an albatross around my neck." Unless you actually happen to be related to sea birds, the albatross here is a metaphor meaning "burden" or whatever. In the limerick, you actually are inactive (or lazy, torpid, whatever) so the concept of a metaphor doesn't seem to apply.
