Pronunciation

  • US: /ˈmɛn.stɹu.əl/, /ˈmɛn.stɹəl/[1]

Etymology

It is inherited from Middle English menstrual, also menstruel,[2] borrowed from Middle French menstruel (recorded in Old French about 1268) and directly borrowed from Latin mēnstruālis (“monthly; having monthly courses”),[3][4][5][2] from mēnstruus (“of a month, monthly”),[4][5][6] from mēnsis (“month”).[4][5][7] The Latin word for month is a close relative of month and moon,[7][4] and the American Heritage Dictionary traces it to the root Proto-Indo-European *mē-.[8] Merriam-Webster derives it instead from mēnstrua (“the menses”), the neuter plural of the adjective.[9]

Earliest recorded meaning

Of the blood discharged from the womb at monthly intervals: before 1398, in Trevisa's translation of Bartholomaeus Anglicus' De Proprietatibus Rerum.[3][5]

Semantic evolution

In Middle English the word was used in medical writing for a woman able to menstruate and for the menstrual flow, as in menstrual blood and menstrual flux.[2] From 1594 it also had the general sense "monthly, happening once a month",[3][4] occasionally in astronomy;[4] Johnson (1755) gave that sense first.[10] It is now rare or archaic.[3][9] In alchemy, menstrual meant relating to a menstruum from before 1550,[3] and as a noun it named the menstruum itself.[2][3] The botanical sense "lasting a month", of a flower, is recorded from 1866.[3][9] The phrase menstrual cycle names the cycle of ovulation and menstruation.[6]
