ナン, やわ.らか, やわ.らかい

soft

JLPT2 G7 S11 F1269

Originally, 車 vehicle + # (soft) → large, wheeled plow used to turn up soft soil (lying beneath the hard upper layer) → *soft*. For the idea of softness vis–à–vis the turning of soil, compare 農. 軟 replaces with bent, open-mouthed figure (bend → pliable), and this became the standard form of the character.
