The phrase "is alive" does not have a specific etymology since it is derived from the separate words "is" and "alive". However, the individual etymologies for these words can be explained:
- "Is" is a form of the verb "to be" and comes from the Old English word "is", which itself is derived from the Proto-Germanic word "iz". This word has its roots in the Proto-Indo-European language, specifically from the root "es-" meaning "to be" or "exist".
- "Alive" comes from the Middle English word "alyve", which can be split into two parts: "a" (on or on) and "lyve" (live, or having life). "Alyve" has its origins in the Old English word "on līfe", which translates to "in life".
