The phrase "past prime" is composed of two separate words whose etymology traces back to different origins.
1. Past: The word "past" comes from the Old English word "past", which means "passed by" or "gone beyond". It is related to the Middle Low German word "past" and Middle Dutch word "past", both with the same meaning. The Old English word is derived from the Proto-Germanic root "*pistiz", which means "beyond". This word has evolved over time to its modern usage, indicating something that has occurred or is no longer current.
2. Prime: The word "prime" comes from the Latin word "primus", meaning "first" or "foremost". This Latin word is derived from the Proto-Indo-European root "*prem-", which means "first" or "foremost".
