"Wast on the lookout" is an archaic phrase that originates from Middle English and has since fallen out of common usage. It combines two words, "wast" and "on the lookout," to convey a sense of vigilance or attentiveness.
The term "wast" derives from the Middle English verb "wisten," meaning "to know" or "to be aware." It suggests possessing knowledge or being acquainted with something. In the context of this phrase, "wast" emphasizes an individual's familiarity or understanding of their surroundings.
Meanwhile, "on the lookout" expresses the idea of being watchful or observant, often in anticipation of a particular event or for potential dangers. This phrase is typically used to denote an individual's heightened state of awareness or attentiveness, as if on guard.
Combining these two elements, "wast on the lookout" therefore connotes an individual who is both knowledgeable and watchful. It implies a state of being keenly aware and actively searching for something, possibly paying close attention to their surroundings to detect any changes, threats, or opportunities.
Overall, "wast on the lookout" describes a person exhibiting both cognizance and vigilance, indicating a readiness to act or respond accordingly. Although rarely used nowadays, understanding the phrase can provide insight into the historical usage of language and enrich one's comprehension of literary works from medieval times.
