A person who augurs or foretells the future; someone who makes predictions or interprets omens.
From augur (to predict/foretell) + -er (one who does). Augur comes from Latin augur (diviner, soothsayer), possibly connected to avis (bird) since Roman augurs read bird behavior to predict futures.
Roman augurers literally watched birds flying and interpreted their movements to predict the future—it sounds silly now, but this job was so important that Roman leaders wouldn't make decisions without consulting them!
