The verb is from Middle English ^((please verify)) surgen, possibly from Middle French sourgir, from Old French surgir (“to rise, ride near the shore, arrive, land”), from Old Catalan surgir, from Latin surgō, contraction of surrigō, subrigō (“lift up, raise, erect; intransitive rise, arise, get up, spring up, grow, etc.”, transitive verb), from sub (“from below; up”) + regō (“to stretch”), ultimately from Proto-Indo-European h₃réǵeti (“to straighten; right”), from the root h₃reǵ-; see regent. Doublet of source and sourd. The noun is from the verb.
From Middle English sourge, of uncertain origin. In the earliest examples, translating Old French sourgeon (modern French surgeon), from sourge- (which the Middle English term is probably from), the present stem of sourdre, from Latin surgō (“to rise”).
