jump
狘 centers on a sudden, forceful upward motion: a jump or leap. The single given meaning is narrow, so treat the core idea as a quick, animal-like springing action.
狘 combines the beast radical 犭 with 戉, which likely acts as a phonetic component. The exact historical development is uncertain, but the structure suggests a phono-semantic compound where 犭 indicates an animal-related action and 戉 provides the sound.
A wild beast 犭 with a weapon-like shape 戉 suddenly springs up: imagine a startled animal jumping when a blade flashes nearby.
For ケツ, picture a beast making a sharp 'kets' sound as it jumps: the sudden noise cues ケツ while the animal leaps.
