Root Explanation

Aminopyrine is formed from "amino" (from the Latin "amino", meaning containing an amino group) and "pyrene" (from the Greek "purēn", meaning fire or to burn). The word refers to a compound that contains an amino group and is related to pyrene, which is associated with burning or combustion.
