transitive verb (mon·i·tored ; mon·i·tor·ing \\ˈmä-nə-t(ə-)riŋ\\) DATE 1924 : to watch, keep track of, or check usually for a special purpose English Etymology monitor 1540s, "senior pupil at a school charged with keeping order, etc.," from L. monitor "one who reminds, admonishes, or checks," from monere "to admonish, warn, advise," related to memini "I remember, I am mindful of," and to mens "mind," from PIE base *men- "to think" (see mind (n.)). The lizard so called because it is supposed to give warning of crocodiles (1826). Meaning "squat, slow-moving type ofironclad warship" (1862) so called from name of the first vessel of this design, chosen by Capt. Ericsson because it was meant to "admonish" the Confederate leaders in the U.S.Civil War. Broadcasting sense of "a device to continuously check on the technical quality of a transmission" (1931) led to special sense of "a TV screen displaying the picture from a particular camera." The verb is attested from 1924. Related: Monitored; monitoring.
