The phrase "on alert" derives from the word "alert", which has its roots in the late Latin word "alertus", meaning "vigilant" or "watchful". This Latin word is formed by adding the prefix "ad-" (meaning "toward" or "for") to the verb "alertere" or "allēgere" (meaning "to awaken" or "to rouse"). Over time, the term "alert" came to be used in English to describe a state of readiness or vigilance. The phrase "on alert" therefore indicates a condition of being prepared and watchful.
