Etymology: This is the plural of "thrombocytopenia", so the story belongs to the singular. The term was built from Greek parts: "thrombos" meaning a lump or clot, "kytos" meaning a hollow vessel or cell, and "penia" meaning poverty or lack. Joined together, they describe a shortage of clotting cells in the blood. The "penia" element is the surprising piece. In ancient Greek, "penia" meant poverty, the state of having too little, and it traces back to "penes", a word for a worker who must labour for a living rather than a rich man who lives off his means. Medical terminology borrowed it as a suffix for deficiency, so the same root that once described the poor now names a count that has fallen too low. "Thrombocyte" was itself a modern coinage, formed in English from "thrombo-" and "-cyte" (cell), and the medical compound "thrombocytopenia" was built on it with the connecting vowel "-o-". The plural simply adds "-s" to the English form.
