Etymology
the word "overrun" is a phrasal verb formation native to english, combining the germanic prefix "over-" with the core verb "run". its earliest senses in middle english pertained to physical movement, such as running over a surface or spreading across a territory like a flowing liquid. this literal sense of flowing or spreading "over" a boundary naturally evolved into the modern meanings of invasive occupation, exceeding limits, and military conquest. the conceptual logic connects the physical action of running beyond a line to abstract violations of temporal, spatial, or defensive limits.
Analysis
Structure: over + run
"over" (from old english "ofer", meaning above, across, or beyond, functioning as an intensifying or locative prefix); "run" (from old english "rinnan"/"iernan", meaning to flow or move swiftly, functioning as the core verb root).
