Etymology: "Efficacities" is simply the plural of "efficacity", a noun meaning the ability to succeed or produce an intended result. Its ancestor is "efficacité" in Middle French, from which English took the base "efficacity" and then the "-acity" ending, a suffix that English often attaches to adjectives ending in "-ax" or "-ac" to form nouns of quality. Behind that French form lies Latin "efficax", meaning effective or able to bring something about, built from "efficere", to accomplish or work out. The Latin root reaches back to "facere", to make or do, so the word's core idea is literally making something happen.

Synonyms: effectiveness, efficiency, potencies, capabilities, competencies
