Gentle

gentle, peace, satisfactory, appropriate

Mnemonic

A claw descends toward a woman, but instead of striking, it softly strokes her hair. She doesn't flinch — she knows this claw has learned to be gentle. Every conflict is settled the same way: the claw reaches out, the woman stays calm, and a gentle compromise is found.
Additional thoughts
Picture a monster's claw learning tenderness from a composed woman — the claw hovering above, then softly touching down. The image of expected violence turned into calm resolution cements the meaning.
Quick recall
A claw hovers over a woman but lands softly — Gentle compromise replaces aggression.
