Etymology: "Oedemata" is the plural of "oedema," the form that English medical writers borrowed from Greek and that gives the word its scientific, Latinate look. The Greek source, "oidēma," means "swelling," from "oidein," to swell, and it passed into English as a technical term for the abnormal accumulation of fluid in tissues. In the Greek plural, the singular ends in "-ma," so the plural takes "-mata," which is why English medical texts often keep this form instead of adding a simple "s." Because the word is a plural, it is the form used when discussing more than one case or more than one affected area of the body. Speakers and writers today commonly use "edemas" for the plural as well, and that form is widely accepted in modern medicine.

Synonyms: edemas, swelling
