The word 'spiritualist' is built upon the ancient Latin concept of spiritus, which originally meant 'breath'—the vital force that animates life. This concrete meaning evolved abstractly to signify the soul, courage, and the immaterial essence of a being. The suffix -alis was added to form the adjective 'spiritual,' pertaining to this non-corporeal realm. Finally, the agent suffix -ist was attached, creating a term for a person who adheres to the doctrine or practices related to the spirit world, thus charting a lexical journey from the physical act of breathing to a philosophy concerning communication with disembodied consciousness.
