Origin of Protoplasm

  • From German Protoplasma, coined by Czech physiologist Johannes Evangelista Purkinje, from Ancient Greek πρῶτος (prōtos, “first") + πλάσμα (plasma, “something molded"). The word was in Late Latin, meaning "first created thing," and may have existed in Medieval Greek in a different sense.
