Burglarproof → It is formed from "burglar" (from the Middle English *burglar*, meaning a thief who breaks into a building) and "proof" (from Old French *proef*, meaning to test or to withstand). The word "burglarproof" means designed to withstand or prevent burglary.
Think of a 'burglar' as someone who breaks into a building, and 'proof' means to withstand. So, burglarproof means something that can withstand a burglar's attempts.
