敢

Right indexing strike radical (the rap radical, abbreviated form of 攴) - a hand holding a stick. Combined with the left side's ear-seizing image, the whole character reads 'boldly striking and seizing' - a daring act of force. Same radical anchors many forceful-action verbs: 改 (alter), 散 (scatter), 救 (rescue), 攻 (attack).

Left side combines a small stroke at the top with the ear 耳 below - depicting a hand reaching down to seize an animal's ear or tusk, the iconic gesture of a daring act in oracle-bone script. The fused top-stroke (1 contraction stroke) plus full 耳 below give the 'seizing dangerous prey' image that grounds the meaning 'to dare'. Standalone 耳 = 6 strokes; here 7 because the grasping mark is fused in.
