Caduceus is a noun referring to the staff entwined with two serpents, symbolically associated with commerce, negotiation, and heralds in ancient myth. In modern times, it is most often linked to medicine through misassociation with the Rod of Asclepius. The word is stressed on the first syllable and has a crisp, Lilting two-syllable onset before a three-syllable tail, yielding a formal, almost ceremonial tone in usage.
