Etymology
The word "vigilance" entered English in the late 16th century from Latin vigilantia, which derives from vigilare meaning "to keep awake, watch". The Latin root vigil itself is traceable to the Proto-Indo-European root weg-, meaning "to be strong, lively", a sense that connects wakefulness with vitality. The literal concept of staying physically awake for a night watch evolved into the modern abstract meaning of sustained mental attention and caution against threats. The suffix "-ance" solidifies this active state into a noun denoting the quality or condition of being watchful.
Analysis
vigil: from latin vigil meaning "awake, watchful". functions as the core root conveying the sense of alertness. ance: a suffix of latin origin (-antia) used to form nouns indicating a state or quality.
