to jolt
趷 centers on a sudden, sharp movement: to jolt or be jolted.
趷 combines 足 (foot) with 乞, which likely contributes the sound. The exact historical development is uncertain.
The left side is 足 (foot), and the right side 乞 looks like a bent figure. Imagine a foot hitting an uneven surface, causing a sudden jolt.
For ゲ, imagine a foot jolting against a gate: gate -> ゲ, and the impact makes you jolt.
