The phrase "put to rest" is a combination of two separate words, each with its own etymology:
1. "Put": The word "put" originates from the Old English word "putian", which means "to thrust, push, or put forward". This word can be traced back to the Proto-Germanic word "putōną" and the Proto-Indo-European root word "beudh-", meaning "to be awake, observe". Over time, "put" has evolved into its current meaning of "to place, set, or place in a particular position or location".
2. "Rest": The word "rest" comes from the Old English word "restan", which means "to cease from action or motion, to be at ease". It can be traced back to the Proto-Germanic word "rastijaną".
