“hemorrhage,” “bursting out,” “profuse discharge of blood” — Noun-forming compound suffix — “condition of violent or profuse bleeding/discharge”
The word entered English in the 1540s as hemorrhage (noun/verb), borrowed from French hémorragie, from Late Latin haemorrhagia, from Greek αἱμόρροια (haimorroia) — literally “a bursting-out of blood” (haima “blood” + rhagia “a bursting”). The suffix form -rrhagia in medical compounds appeared in the 1800s. The root rhēgnymi (“to burst, to break”) connects -rrhagia to the entire rupture and hemorrhage suffixes: menorrhagia (meno- + rrhagia → profuse menstrual bleeding), melorrhagia (melo- + rrhagia → profuse discharge of menses), and rhinorrhagia (rhino- + rrhagia → violent nasal bleeding). The compound suffix-rrhagia is productive in surgery, gynecology, and hematology: e.g., uterine hemorrhage, cerebral hemorrhage, rectorrhagia, splenorrhagia, and urethrorrhagia.
