The word "door lock" is composed of two distinct components: "door" and "lock".
- "Door" originated from the Old English word "dur" or "duru", which can be traced back to Proto-Germanic *durz. This term has cognates in other Germanic languages, such as German "Tür" and Dutch "deur".
- "Lock" comes from the Old English word "loc", which is related to Old Norse "loka" and Middle Dutch "locke". It ultimately stems from Proto-Germanic *lukkaną, meaning "to close" or "enclose".
The combination of these two words gave rise to "door lock" as a reference to the mechanism used to secure or close a door.
