[Middle English trenche, from Old French, a cutting, slice, from trenchier, to cut, from Vulgar Latin *trincāre, perhaps partly from Latin *trīncāre, to cut in three (from earlier *trīnicāre : Latin rīnī, three each, triple; see trei- in Indo-European roots + Latin -icāre, as in duplicāre, to double, split in two; see duplicate) and partly from a Gaulish root *trink-, to cut, behead, found in Late Latin trincus trincus, a kind of gladiator who was subject to particular Gaulish customs and probably fought until beheaded (of Gaulish origin, perhaps ultimately from a pre-Roman substrate root *trenk-, to cut, or perhaps akin to Latin truncus, trunk; see terə in Indo-European roots).]
