Origin of spy

Middle English spien, aphetic variant of earlier espien "to espy", from Old French espier (“to spy") (espie "a spy"), from Frankish *spehōn (“to spy"), from Proto-Germanic *spehōnÄ… (“to see, look"), from Proto-Indo-European *spek- (“to look"). Akin to Old High German spehōn, spehhōn "to scout, look out for, spy" (German spähen "to spy"), Middle Dutch spien "to spy", Dutch bespieden "to spy on".
