bow
弨 centers on a bow, specifically one that is unstrung and relaxed, with its ends curving outward. The core idea is a bow in its resting, curved state.
弨 combines 弓 (bow) with 召, which likely contributes the sound. The character specifically refers to a bow that is unstrung and relaxed, with its ends curving outward.
The left side 弓 is a bow, and the right side 召 looks like a curved blade and mouth. Picture a bow that is unstrung and relaxed, its ends curving outward like a blade, ready to be called into action.
For ショウ, imagine a show of archery where the bow is unstrung and relaxed between performances: show -> ショウ, and the bow rests in its curved state.
