Possibility removes an objection that an unusual claim is impossible. Condition identifies a quality, and degree shows its intensity. Reinforcement deepens an already known state; beautification heightens attractiveness; disfigurement evokes aversion; making remarkable presents an unexpected image.
When the intended effect concerns the comparator, reversed simile inverts the expected benchmark to create hyperbolic praise, while preoccupation reveals the speaker's pressing need or desire. These effects should not be conflated.
Finally, if the speaker seeks only to say that two things share a feature, a judgment of mutual likeness may be preferable, though a simile remains possible for a special rhetorical aim. These distinctions provide the basis for analysing subsequent divisions of simile according to its two terms.
