Etymology
The word 'interlock' is a relatively modern English formation, created by combining the Latin-derived prefix 'inter-' with the native English verb 'lock'. The prefix 'inter-' introduces the concept of reciprocity or mutual action between separate entities. The core verb 'lock', with its Proto-Germanic roots related to fastening and enclosure, provides the concrete action. Thus, the literal meaning "to fasten mutually between" evolved into the modern abstract sense of parts or systems connecting or fitting together in a way that their movements or functions become interdependent, creating a single, secure, or coordinated unit.
