Etymology: The Greek verb "oidéō" meant "I swell," and from it came "oídēma," a noun meaning simply "swelling." Greek physicians used the noun for any puffing up of the body, a sense that survives almost unchanged in the modern medical term. The word reached English through New Latin, the scientific Latin that European scholars used for coining technical vocabulary, so "oedema" is a learned coinage built on Greek material rather than something that passed through everyday Latin speech. The spelling is the clearest sign of that route. The "oe" digraph is a faithful transliteration of the Greek diphthong, which English writers preferred for medical terms for centuries. The American "edema" simplifies it to a single "e," the same change seen in words like "anemia" and "anesthesia," where the classical digraph was dropped on the other side of the Atlantic.
