scrofula (n.)youdaoicibaDictYouDict[scrofula 词源字典]
c. 1400, scrophulas (plural) from Late Latin scrofulæ (plural) "swelling of the glands of the neck," literally "little pigs," from Latin scrofa "breeding sow" (see screw (n.)). The connection may be because the glands associated with the disease resemble the body of a sow or some part of it, or because pigs were thought to be prone to it. Compare Greek khoirades (plural) "scrofula," related to khoiros "young pig."[scrofula etymology, scrofula origin, 英语词源]
