From German Protoplasma, coined by Czech physiologist Johannes Evangelista Purkinje, from Ancient Greek πρῶτος (prôtos, “first”) + πλάσμα (plásma, “something molded”). The word 'Protoplasmus' was in Late Latin, meaning "first created human" (i.e. Adam), and may have existed in Medieval Greek in a different sense.
