Etymology

From Middle English sours, from Old French sorse (“rise, beginning, spring, source”), from sors, past participle of sordre, sourdre, from Latin surgō (“to rise”), which is composed of sub- (“up from below”) + regō (“lead, rule”), ultimately from Proto-Indo-European *h₃réǵeti (“to straighten; right”), from the root *h₃reǵ-. Doublet of surge.
