flutter, wave, bow to, obey, seduce
靡 centers on yielding or bending under influence: fluttering or waving in the wind, bowing in submission, obeying, or being seduced away from one's own will.
靡 combines 麻 (hemp) with 非 (not, wrong), suggesting hemp fibers that are not rigid and thus bend or flutter easily. The exact historical development is uncertain, but the character likely expresses pliancy or yielding.
Hemp 麻 fibers are not 非 stiff; they flutter in the wind, bow down, and are easily swayed—just like someone who obeys or is seduced.
For ヒ, imagine the hemp fibers fluttering in a gentle breeze, making a soft 'hee' sound: hee -> ヒ, as they wave and bend.
