Etymology
The word 'mifepristone' is a modern pharmaceutical coinage, not derived from classical roots. Its structure was artificially constructed by its developers in the 1980s. The components 'mife-', 'pris-', and '-tone' were selected primarily for their chemical nomenclature logic, with 'mife-' referencing specific molecular groups, 'pris-' alluding to a related hydrocarbon structure, and '-tone' being a conventional suffix for steroid-based drugs. Therefore, its etymology is not a story of linguistic evolution but of deliberate, technical construction for scientific identification.
Analysis

mife (coined element, from the chemical designation "mid-19 phenyl-aminopropoxy") + pris (coined element, from "pristane", a type of hydrocarbon) + tone (coined element, common suffix for steroid compounds)
