Pneumon-,

Etymology: Origin of the term Etymology of the etymological term “pneumonaut” comes from two Greek words: “pneumatos” - “breath”, “pneuma” - wind; in this sense, "pnemnonaut" literally means one who breathes air. The same root is in the words “pneumatology” and “pneumatos”.

However, these words do not mean breath or portable air, but refer to the field of worldview: “pneuma” is an immortal life force, a breath of being that breathes life into its creations, a spiritual essence, an element; “pneumatics” - “pneumatic principles”, “spirit, soul”; “pneumatic” - soul (modern term), “pneumosacred” (airy spirit, vaporous kernel in retorts and distillation jugs), pneumatic (related to “pneuma”) - for example, a pneumatic coupling for connecting gear wheels. According to Hippocrates, humans are composed of pneuma and blood. The phrase "a medicine contains one spirit and two sides" means that the medicine includes the pneuma itself, acting through the blood.
