Morphology

interlock = lock (transparent) = inter + lock

The noun denotes a device that performs the action 'to interlock' (inter- + lock) and the meaning is directly inferable from the base.

Etymology

Interlock comes from the parts inter- meaning 'between' and lock meaning 'fasten'. Think of a safety device that 'locks' two parts together until it is safe to move, so an interlock prevents a machine or car from starting unless conditions are right.
