Etymologically, the entry records: From Middle English spien, aphetic variant of earlier espien (“to espy”), from Old French espier (“to spy”), from Frankish *spehōn (“to spy”), from Proto-Germanic *spehōną (“to see, look”), from Proto-Indo-European *speḱ- (“to look”). Akin to German spähen … Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is spy, spelled S-P-Y, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.

Definition

  1. 1
    A person who secretly watches and examines the actions of other individuals or organizations and gathers information on them (usually to gain an advantage).
  2. 2
    A defensive player assigned to cover an offensive backfield player man-to-man when they are expected to engage in a running play, but the offensive player does not run with the ball immediately.

Etymology

From Middle English spien, aphetic variant of earlier espien (“to espy”), from Old French espier (“to spy”), from Frankish *spehōn (“to spy”), from Proto-Germanic *spehōną (“to see, look”), from Proto-Indo-European *speḱ- (“to look”). Akin to German spähen (“to spy”), Dutch spieden (“to spy”). The noun displaced native Old English sċēawere (literally “watcher”), which was also the word for "mirror." In this sense, the verb displaced Old English sċēawian, which was also the word for "to watch" and became the Modern English word show. Distant cognate vie PIE with Latin speculātor, Ancient Greek κατάσκοπος (katáskopos). Compare typologically Russian согляда́тай (sogljadátaj) (akin to гляде́ть (gljadétʹ)).
