Etymology: The surprise here is how much of this word is built from Latin and Greek pieces that were never used together in antiquity. "Progestogen" was put together in English in 1941, from "pro-", the Latin "gestō" meaning "to bear, to carry", a connecting "-o-", and "-gen", a suffix meaning something that produces or generates. The name describes the hormone's job: it supports a pregnancy, so it helps the body carry a developing embryo. The "-gen" ending has its own history. It comes from the Greek "génos", meaning birth or race, which gave the suffix its sense of "producing" or "giving rise to". Ancient Greek used forms like "-genḗs" as adjectives, and these passed through French "-gène" into English. Chemists and physiologists of the twentieth century drew on this stock of classical building blocks to name new substances, so the Greeks and Romans never encountered the hormone itself. Because the word is a plural, "progestogens" refers to the whole family of such substances. Its meaning is therefore the group as a class, rather than any single compound.
