gavel
敔 centers on a gavel, a small ceremonial mallet used to strike a surface for order or attention. Its meaning is narrow and concrete, with no clear extended senses.
敔 combines 吾 (possibly phonetic) and 攵 (hand holding a stick), suggesting a striking action. The exact historical development is uncertain, but it likely represents a mallet or gavel used ceremonially.
The left side 吾 looks like a block with a mouth, and the right side 攵 is a hand holding a stick. Imagine a judge's hand striking a wooden block with a gavel to call for order.
For ギョ, picture a judge using a gavel while saying 'Gyo!' to get attention: Gyo -> ギョ.
