What does menorrhea mean?
Menorrhea is the medical term for menstruation, the recurring process by which the lining of the uterus is shed and discharged from the body. Although its name may sound clinical or suggest a disorder, it can denote normal menstruation without implying that anything is wrong. The term is especially useful in medical and comparative contexts because it distinguishes the ordinary menstrual process from related conditions such as menorrhagia, in which menstrual bleeding is unusually heavy or prolonged, and amenorrhea, in which menstruation is absent. In general conversation, most people say “period” or “menstruation,” but menorrhea appears in clinical writing, health information, and discussions of reproductive health. Its combination of Greek elements meaning “month” and “flow” accurately reflects its close relationship to the monthly menstrual cycle.

Where does menorrhea come from?
The word combines the Greek roots mēn, meaning “month,” and rheē, meaning “flow.” These elements literally express the idea of a monthly discharge. The English medical term developed from this Greek combination and has a British variant spelled “menorrhoea.” Its relatives include catamenia, amenorrhea, and menstrual, all connected with the same broad concept or underlying roots.
