Describing something that is literal and not using figures of speech or symbolism.
The instructions were nonmetaphorical, making them easy to understand.
Nonmetaphorical → It is formed from "non-" (meaning not) and "metaphorical" (from Greek "metaphorikos", meaning figurative or symbolic). The word "nonmetaphorical" means not figurative or symbolic, referring to a literal interpretation.
Think of 'not' ('non-') and 'figurative' ('metaphorical') to remember that 'nonmetaphorical' means something that is literal, not using symbols.
