blend

Etymology

From Middle English blenden, either from Old English blandan, blondan, ġeblandan, ġeblendan or from Old Norse blanda (“to blend, mix”) (which was originally a strong verb with the present-tense stem blend; compare blendingr (“a blending, a mixture; a half-breed”)), whence also Danish blande, or from a blend of the Old English and Old Norse terms; both ultimately from Proto-Germanic *blandaną (“to blend; mix; combine”). Compare Middle Dutch blanden (“to mix”), Gothic 𐌱𐌻𐌰𐌽𐌳𐌰𐌽 (blandan), Old Church Slavonic блєсти (blesti, “to go astray”).

noun

That is, none occur in Old or Middle English, nor even in Elizabethan English, with the earliest known example being the rare and now obsolete term tomaxe, a blend of tomahawk and axe. 2018, James Lambert, “A multitude of ‘lishes’: The nomenclature of hybridity”, in English World-Wide, page 10

   Sepia Delft tiles surrounded the fireplace, their crudely drawn Biblical scenes in faded cyclamen blending with the pinkish pine, while above them, instead of a mantelshelf, there was an archway high enough to form a balcony with slender balusters and a tapestry-hung wall behind. 1963, Margery Allingham, chapter 3, in The China Governess
   Earless ghost swift moths become “invisible” to echolocating bats by forming mating clusters close[…]above vegetation and effectively blending into the clutter of echoes that the bat receives from the leaves and stems around them. Many insects probably use this strategy, which is a close analogy to crypsis in the visible world—camouflage and other methods for blending into one’s visual background. 2013 May-June, William E. Conner, “An Acoustic Arms Race”, in American Scientist, volume 101, number 3, pages 206–7
