Borrowed from Ancient Greek κατάρροος (katárrhoos), which is derived from καταρρέω (katarrhéō, “I flow down”), which is composed of κατά (katá, “down”) and ῥέω (rhéō, “I flow”).
catarrh (plural catarrhs)
- (pathology) Inflammation of the mucous membranes of the nose and throat.
1960, P. G. Wodehouse, “XII”, in Jeeves in the Offing:
- “Where I went wrong,” he said, still speaking in that low, husky voice as if he had been a ghost suffering from catarrh, “was in getting engaged to Phyllis Mills.”
