Etymology
From Middle English 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.
