Morphology

deadbolt = dead + bolt (transparent) = dead + bolt

Formed from the clear words 'dead' (immobile/not moving) and 'bolt' (a metal sliding bar), so the meaning is directly inferable.

Etymology

A deadbolt is made of two simple words: dead, meaning 'not moving' or 'fixed', and bolt, meaning a 'metal bar'. So a deadbolt is a bar that stays firmly in place to make a door very secure.
