What does flitched mean?
Flitched is the past tense and past participle of flitch, a largely trade-level term meaning to cut something — most often a log — lengthwise into thick, squared boards called flitches. A sawyer who has flitched an oak trunk has produced substantial slabs that will later be resawn into planks; a butcher who has flitched a side of pork has sliced it into curing pieces. In structural engineering, the related phrase "flitched beam" denotes a timber beam stiffened by bolting metal plates to its sides, a composite design popular from the eighteenth century onward. The underlying noun, flitch, descends from Old English flicce, meaning a side of bacon, giving the word a curious double life spanning both the sawmill and the smokehouse. Today flitched appears almost exclusively in specialist contexts — carpentry, timber milling, heritage building restoration — rather than in ordinary speech.

Etymology of flitched
Flitched derives from flitch, which comes from Old English flicce, meaning a flank or side of a slaughtered pig, a word with cognates in other Germanic languages such as Old Norse. From the butchery sense the term was extended to timber, where a flitch came to mean a thick board sawn lengthwise from a log. The composite engineering notion of a flitched beam arose in the Georgian era, when iron plates were married to timber for added strength.
