Potentiation is formed from "potent" (from Latin "potens", meaning powerful or having power) and the suffix "-ation" (meaning the action or process of). The word describes the process of making something more powerful or effective.
Think of 'potent' meaning powerful, and '-ation' indicating a process. So, potentiation is the process of making something more powerful.
