Etymology: "Ostreophagist" is built from two Greek-derived parts. The first, "ostreo-", comes from the Greek "ostreon", meaning oyster, a combining form that English uses in technical vocabulary. The second, "-phagist", comes from the Greek "phagos", meaning eater, with the suffix "-ist" marking a person who practises or follows something. Put together, the word describes someone who eats oysters, or more precisely, someone whose diet is built around them. The word is a coinage in the style of scientific and learned English, assembled from classical elements rather than inherited from ancient Greek speakers, who had no word for an oyster-eater of this kind. Its parallel forms follow the same pattern, such as "ichthyophagist" for a fish-eater or "entomophagist" for someone who eats insects, so the word belongs to a family of terms built on the same "-phagous" and "-phagist" endings.
