crush, break, sprain, discourage
挫 centers on forceful deformation or suppression: physically crushing, breaking, or spraining something, and metaphorically discouraging or dampening a person's spirit.
挫 combines 扌 (hand) with 坐, which likely contributes the sound and the idea of sitting or pressing down, suggesting a hand pressing or crushing something.
A hand 扌 pressing down on 坐 (sitting) crushes what is beneath it, like a hand breaking a fragile object or spraining a joint by forcing it down.
For ザ, imagine the crushing hand making a sharp 'za' sound as it breaks something: za -> ザ, and the hand crushes down.
