archer's glove
弽 centers on a protective glove worn by an archer, specifically the glove used to draw the bowstring.
弽 combines 弓 (bow) with 枼, which likely contributes the sound and relates to a flat, leaf-like object, suggesting a glove used with a bow.
The left side 弓 is a bow, and the right side 枼 looks like a hand-shaped leaf. Picture an archer wearing a leaf-like glove to protect the hand while drawing the bow.
For ショウ, imagine an archer showing off the glove before a shot: show -> ショウ, and the glove is essential for the bow.
