dapple

Origin

Uncertain. The adjective is first attested circa 1550 though the first element is already attested in dapple-grey as early as 1386, in Middle English, and later as dappled circa 1400; the OED suggests either: * a back-formation from dapple-grey, itself a variant of apple-grey, compare possible cognates all said of horses: Old Norse apalgrár (whence Norwegian abildgrå and Swedish apel-grå), German apfelgrau. Compare also French pommelé (“dappled”), from pomme (“an apple”); or, * a relation with Icelandic depill (“a dot, spot”). The noun and verb are both later attested likely as back-formations.
