The new smartphone is shockproof, so it can survive drops without breaking.
Shockproof → It is formed from "shock" (from Old English *sceocca*, meaning a sudden impact or disturbance) and "proof" (from Old French *proef*, meaning resistant or impervious). The word "shockproof" means resistant to sudden impacts or disturbances.
Think of something that is 'resistant' ('proof') to a 'sudden impact' ('shock') — that's why shockproof means it can withstand shocks.
