skill, ability in handicraft a craft, an art, calling, trade, accomplishment
秇 centers on skilled handiwork: a craft, art, or trade practiced with ability and accomplishment. The calling sense is a natural extension of a practiced skill.
秇 is a rare character. It visually combines 禾 (grain) and 丸 (round), but the historical origin is uncertain. It may have been used as a variant of 藝 (art, skill), but the exact development is unclear.
Picture a grain stalk 禾 being shaped into a perfect round ball 丸 by a skilled craftsperson. The transformation from raw grain to a crafted sphere represents art and skill.
For ゲイ, imagine a skilled artist painting a gate: gate -> ゲイ, and the gate becomes a masterpiece of craft.
