What does menstruation mean?
Menstruation is the recurring physiological process in which the uterine lining thickens and then breaks down, typically once in the course of each menstrual cycle. The shed tissue, along with blood, leaves the body through the cervix and vagina. The process commonly begins during puberty and continues until menopause, although its timing, duration, and symptoms can vary considerably. It is a normal part of reproductive health, though pain, heavy bleeding, or irregular cycles can indicate a medical concern requiring advice. In clinical and educational settings, menstruation is preferred as a clear, respectful term, while 'period' and 'menses' are common everyday alternatives. The vocabulary is useful whenever discussing reproductive health, menstrual cycles, and related clinical care.

Where does menstruation come from?
The English word derives from Latin menstruatio, a form of the verb menstruare, meaning 'to menstruate.' That verb is based on mensis, meaning 'month,' referring to the approximately monthly character of the process. The related English forms 'menstrual' and 'menstruate' were borrowed through Latin, while 'month' reflects the same Latin root. The connection with the calendar month is visible in the word's historical naming of a recurring process.
