Archae
It could be both, but it's definitely a prefix, as in archenemy.
It means first as in archaeology which means going back to the people. SO archae means first.
Archae are decomposers that commonly feed on dead decaying organisms. They are often found at the bottom of the ocean floor.
The Greek word for archae is αρχαιολογία (archaiología), which translates to "archaeology" in English. It is the study of human history and prehistory through the excavation of sites and the analysis of artifacts and other physical remains.
