Etymology: "Ichthyovorous" is built from two Greek elements. The first, "ichthyo-", comes from Greek "ichthys", meaning "fish", and appears in English scientific terms such as ichthyology, the study of fish. The second, "-vorous", comes from Latin "vorax", "voracious" or "greedy for food", from the verb "vorare", "to devour", and gives English words like carnivorous and herbivorous. Joined together, the parts describe an animal that devours fish. The pattern is a deliberate one: naturalists in the 18th and 19th centuries built many such terms by attaching a Greek or Latin root for a food to "-vorous", so that a diet could be named in a single word. The word therefore belongs to a family of scientific coinages rather than to the everyday vocabulary of ancient speakers, who had no need for a term describing a fish-eating animal in those exact terms.
