The word voluntarism is built upon the Latin root volunt-, meaning "will," which itself derives from the verb velle (to wish, to will), a descendant of the Proto-Indo-European root welh₁- meaning "to wish, to will." The suffix -ary transforms this root into the adjective "voluntary," pertaining to actions arising from one's own free will. Finally, the addition of the Greek-derived suffix -ism crystallizes the concept into a named doctrine or principle. Thus, the term's literal construction—"the doctrine pertaining to the will"—logically evolved to describe both the philosophical emphasis on the will's primacy and the social practice based on freely given, uncoerced action.
