"Wast on lookout" is an archaic expression that combines two words: "wast," the archaic second person singular form of the verb "to be" in Middle English, and "lookout," a noun referring to a person who watches carefully for something or someone.
The term "wast" indicates that the phrase originates from Middle English, the language spoken in England between the 11th and 15th centuries. Specifically, "wast" takes the place of the modern form "were" or "was." Thus, "wast on lookout" literally translates to "were/was on lookout" in contemporary English.
"Lookout" refers to a person or a place from where surveillance is conducted, often in order to keep watch for possible danger, threats, or anticipated events. It implies a heightened state of awareness or vigilance.
When combined, the phrase "wast on lookout" indicates that someone in the past, using the second person singular form, was in a state of observation, vigilance, or alertness. It suggests that the individual was diligently scanning their environment for potential hazards, monitoring a specific area, or searching for something of importance. This phrase demonstrates an intention to actively engage in the act of looking out or being watchful.
However, it is essential to note that "wast on lookout" is an outdated and rarely used phrase. The use of "wast" instead of the modern "were" or "was" and the archaic tone may make it unfamiliar and confusing to most contemporary English speakers.
