Also found in the 19th cent. in adaptations immediately from French (as perhaps proctorrhagia n. at procto- comb. form , nephrorrhagia n. at nephro- comb. form ) and German (compare lymphorrhagia n.). Formations within English are found from the first half of the 19th cent. onwards, earliest in pneumorrhagia n. at pneumo- comb. form 2. Combining with first elements ultimately of Greek origin. Compare French -rragie (formations in which are found from at least end of the 18th cent. onwards), German -rrhagie.
