Describing something that helps to lessen or prevent the effects of shock.
The antishock design of the backpack protects fragile items during travel.
Antishock is formed from "anti-" (meaning against) and "shock" (from Old English "sceocca", meaning to strike or hit). The word describes something that works against or mitigates the effects of a shock.
Think of 'against' ('anti-') something that 'strikes' or 'hits' ('shock') — that's why antishock refers to measures that counteract shock.
