spy

spy: [13] A spy is etymologically someone who ‘looks’. The word was adapted from Old French espie ‘watcher, spy’, a derivative of espier ‘watch, spy’ (from which English gets the verb spy, and also espy [14] and espionage [18]). This in turn was formed from the borrowed Germanic base *spekh- (source of German sp?hen ‘reconnoitre, watch’ and Swedish speja ‘spy, scout’), which went back ultimately to Indo- European *spek- ‘look’ (source of English inspect, spectator, etc).
=> espionage, expect, inspect, special, spectator

spy (v.)

mid-13c., "to watch stealthily," from Old French espiier "observe, watch closely, spy on, find out," probably from Frankish *spehon or some other Germanic source, from Proto-Germanic *spehon- (cognates: Old High German *spehon "to look out for, scout, spy," German sp?hen "to spy," Middle Dutch spien), the Germanic survivals of the productive PIE root *spek- "to look, observe" (see scope (n.1)). Old English had spyrian "make a track, go, pursue; ask about, investigate," also a noun spyrigend "investigator, inquirer." Italian spiare, Spanish espiar also are Germanic loan-words. Meaning "to catch sight of" is from c. 1300. Children's game I spy so called by 1946.

spy (n.)

mid-13c., "one who spies on another," from Old French espie "spy, look-out, scout" (Modern French épie), probably from a Germanic source related to spy (v.).
