Antimeria is one of my favorite rhetoric devices. It is the application of a word outside of its lexical category – e.g., using an adjective as a noun or a noun as a verb (in this case also autologically called ‘verbing’!). Even with the words repurposed ad hoc, the missing semantics are filled in by context and their meaning is easily understood.
When particular uses become common enough, polysemes are born.
The slog is giving me a case of the sads.
I can’t computer very much with the slog gnawing at my brain.
Thanks to the slog, I feel like I’m stupiding all over the place.
Polysemy is the semantic relation among identical words of affiliated or derived meaning. A polyseme can be as simple as a word with multiple similar contexts (mattress pad / paw pad / mouse pad), but they are more interesting and useful when they cross part-of-speech borders. If we say “He will bat the bat with a bat,” bat (swat) and bat (baseball) are polysemes, whereas they are merely homonyms with bat (animal).
The slog makes you slog through your creative endeavors.
