Espionage

noun (uncountable)
/ˈɛspɪənɑːʒ/
The practice of covertly gathering intelligence about another state's political, military, economic, or technological secrets, typically through human intelligence (HUMINT) networks, technical surveillance (SIGINT, IMINT), or cyber intrusion. Espionage is considered a violation of sovereignty under international law but is neither explicitly prohibited by treaty — the Vienna Convention on Diplomatic Relations (1961) bars states only from misusing diplomatic immunity for it — nor criminalised by any universal convention. India's external intelligence agency RAW (Research and Analysis Wing, established 1968) and the counter-intelligence function of the Intelligence Bureau (IB, established 1887) are the relevant UPSC institutional actors.

✍️ Usage in a UPSC answer

The 2023 Pegasus controversy, in which Indian journalists, opposition leaders, and ministers were allegedly targeted with Israeli spyware, reignited debate over whether state-authorised cyber-espionage against domestic actors crosses the line from legitimate intelligence collection into unconstitutional surveillance.

🔡 Root

French espionner = to spy; espion = spy (Italian spione); from Old High German spehon = to look out

📜 Etymology

From French espionnage (c. 1793), from espionner ('to spy'), from espion ('spy'), borrowed from Italian spione (augmentative of spia, 'spy'), which traces to Old High German spehon ('to look out, observe carefully'), related to Old English spyian ('to spy') and ultimately to a Proto-Germanic root meaning 'to see clearly.' The French form entered English in the late 18th century, associated initially with Revolutionary-era intelligence activities.

🧠 Memory Hook

From espion (French/Italian for spy) — think of a spy with a spy-glass: espy = to spot from a distance. Espionage is the art of espying — looking where you're not supposed to look, on behalf of your government.
