The meaning of 'Poros' is almost entirely elusive. The Etymologies are of little help; they list a word-root, por-, that seems promising until we realize it means 'flour'. Nor does the name seem to have evolved from phor-, since this implies 'north' while the Poros is emphatically in the south. It is conceivable that the name contains -ros, meaning 'spray'.
