Origin: 1250–1300; ME turbut < AF; OF tourbot < ML turb(ō) turbot (L: top; appar. applied to the fish because of its outline; see turbine, turbit) + OF -ot n. suffix

[Middle English turbut, from Old French tourbout, probably of Scandinavian origin; akin to Old Swedish törnbut : törn, thorn + but, flatfish; see bhau- in Indo-European roots.]
"large flat fish," c.1300, from O.Fr. turbut (12c.), probably from a Scand. source (cf. O.Swed. törnbut, from törn "thorn" + but "flatfish;" see halibut). But OED says of uncertain origin and speculates on a connection to L. turbo "spinning top."
