pneumo-, pneum-, pneumono-, pneumon-
(Greek: lung; breath, breathe)
2. In theology, the Spirit of God; the Holy Ghost.
3. The life-giving principle.
According to the school of medicine in ancient Alexandria, life was associated with a vapor called the pneuma.
The belief in pneuma was called pneumatism. In hindsight, pneumatism was an early attempt to explain respiration, or breathing; which is, indeed, the "life-giving principle".4. Etymology: from Greek pneuma, "breath, wind, air" or "that which is breathed" or "blown"; from pnein, "to blow"; which is considered to be from an imitative origin.
It exists today in the act of blowing out the candles on a [festival] birthday cake.
