“Bombast, an old Swabian name, has inevitably given rise to the idea that Paracelsus's bluster and arrogance lie at the root of the word "bombastic." One feels that it ought to be so, but it is not. Baum means "tree" in German (in the Swabian dialect it is rendered Bom), and Baumbast is the fibrous layer of a tree's bark. But in the sixteenth century "bombast" had also come to mean cotton padding, inappropriately derived from bombax, the medieval Latin name for the silkworm, and it is from this origin that the connotation of puffed up derives.”
