Where does monitored come from?
Monitored derives from monitor, which comes through Old French from Latin monere, meaning “to warn” or “remind.” The Latin root also underlies related English words such as monitory, monition, and monitive, all connected with warning, reminding, or admonition. In modern English, monitor developed its present meanings of observing and supervising, which are reflected in the form monitored.
