The etymology of the word “spirit” traces back to the Latin word “spiritus,” meaning “breath,” but also used in broader senses to denote “soul,” “courage,” “vigor,” and ultimately “life.” The Latin “spiritus” is derived from “spirare,” which means “to breathe.” This connection between breath and life or soul is fundamental in many linguistic traditions, reflecting the breath as a sign of life.

From Latin, the term entered Old French as “espirit” and then into Middle English as “spirit.” Over time, its use expanded to encompass various non-physical and metaphysical concepts, including those related to the essence of a human being beyond the physical form, as well as to ghosts and supernatural beings.

The broad and flexible usage of “spirit” in English reflects its Latin roots while also adapting to include a range of meanings involving unseen forces and elements of human consciousness and personality.
