The term "knock loose" is not an individual word with its own dedicated etymology. Instead, it is a phrase made up of two separate words: "knock" and "loose". Therefore, the etymology of each word should be considered separately.
1. "Knock":
The word "knock" can be traced back to Middle English, where it originated from the Old English word "cnocian". This Old English word further evolved from the Proto-Germanic word "knokjanan". The root of "knokjanan" is believed to be imitative of the sound produced when hitting or striking something. Over time, the word "knock" has retained its meaning of striking or hitting something forcefully.
2. "Loose":
The word "loose" comes from Middle English, derived from the Old English word "lós" or "lās".
