Metaphor

metaphor, compare

Mnemonic

A mouth mounted on the wall of the moonbase never gives straight answers — only metaphor. 'Oxygen is the breath of angels,' it says. 'Gravity is Earth's embrace.' The crew at the moonbase must interpret every mouth riddle to operate the station and stay alive.
Additional thoughts
Picture a literal disembodied mouth bolted to the moonbase wall like a surreal oracle. Every operational instruction it gives is poetic and figurative — never literal. The crew scramble to decode its flowery comparisons before the air runs out. Mouth + moonbase = space oracle of metaphor.
Quick recall
A mouth on the moonbase wall speaks only in metaphor — the crew must decode its riddles to survive.

The keyword for 喩 is metaphor. This kanji refers to the act of explaining or illustrating something by comparing it to something else, making an abstract or difficult concept easier to understand through analogy. It carries the sense of using figurative language or indirect comparison to convey meaning, as opposed to literal description.
