Etymology

The word "voluntary" originates from Latin voluntarius, meaning "of one's free will." The root volunt- reflects the concept of willing or choosing, while -ary turns it into an adjective. Over time, it evolved in Middle English to describe actions performed by choice, emphasizing autonomy and lack of coercion.
