Etymology

The word "ruling" derives from the verb "rule," which originates from Old French "riuler" (to govern) and Latin "regula" (a straight stick, pattern, or principle). The suffix "-ing" transforms the verb into a noun or adjective, denoting the act of governing or the state of being dominant. The progression reflects the concrete idea of a "measuring stick" (regula) evolving into abstract governance.
