Etymology: Adenocarcinomatous is a medical adjective built in layers from Greek roots. The first part, "adeno-", comes from Greek "adēn", meaning "gland," so the word describes a cancer that forms in gland tissue. "Carcinoma" comes from Greek "karkinos," meaning "crab," a name that goes back to the old observation that a tumour's swollen veins and spreading growth looked like a crab's legs and claws. The ending "-omatous" is a suffix meaning "having the nature of" a tumour, so the whole word means "of the nature of a gland-derived carcinoma." Each piece is a classical building block, but the combination is modern. Medical writers assembled such terms in the 19th and 20th centuries as pathology became more precise, so ancient Greek physicians would not have recognised the word, even though every part of it came from their language.
