Etymology: "Codocytes" is the plural of "codocyte," a medical term for a red blood cell with a target-like appearance. The name combines the Ancient Greek "kōdōn," meaning "bell," with the suffix "-cyte," from Greek "kytos," meaning "hollow vessel" and used in biology for cells. The bell image makes sense because the cell's thicker outer ring and thinner centre resemble the profile of a bell. The word is a modern scientific coinage built from classical parts, not a term that ancient Greek writers used for blood. Its pattern follows other cell names such as "erythrocyte" and "leukocyte," which were likewise assembled from Greek roots when laboratory microscopy developed.

Synonyms: target cells, bell cells
