The term "found key" does not have a clear etymology, as it appears to be a combination of two separate words. However, we can look at the individual origins of each word:
1. Found: The word "found" has its roots in the Old French word "fonder" and the Latin word "fundare", meaning "to establish" or "to lay the groundwork". It later evolved to mean "to come upon", as in discovering something unintentionally. This could relate to the concept of finding a key that was previously lost or misplaced.
2. Key: The word "key" derives from the Old English word "cǣg", which stems from the Proto-Germanic language. It originally referred to a device used to secure or open a lock. Over time, "key" also came to represent something that provides a solution or unlocks a mystery.
