The compound adjective "whole-wheat" is a transparent modern English formation. The first element, "whole," descends from the Old English concept of being unharmed, intact, and complete, a notion preserved in its modern sense of "entire." The second element, "wheat," names the specific cereal grain, its Old English root possibly linked to the whiteness of its flour. Combined in the 19th century, the term logically denotes flour or products made from the complete, unrefined wheat kernel, contrasting with refined white flour where the bran and germ are removed. This construction directly reflects a nutritional philosophy that values the entirety of the natural grain.
