Linguistic Origin & Historical Etymology

The term combines 'ocean', derived via Old French and Latin from Greek 'ōkeanós' (the great stream surrounding the earth's disk), and 'trench', from Old French 'trencher' (to cut). Geologically established in the mid-20th century with the advent of modern plate tectonics to describe deep, narrow depressions on the seafloor.
