Perimō is a compound of per and which other verb?

Perimō is indeed a compound verb formed from the prefix "per" and the verb "emō." The prefix "per" generally conveys the idea of "completely" or "through," while "emō," which means "to buy" or "purchase," combines with "per" to give the sense of "to completely take away" or "to destroy." Thus, perimō can be interpreted in a context of something being taken away completely or annihilated. This compound formation is reflective of how Latin often created new words by combining prefixes with existing roots to expand or alter their meanings.
