What does spying mean?
Spying is the practice of secretly watching, listening to, or gathering information about another person, organization, or place. As a noun, it usually describes an activity conducted secretly, such as political spying, industrial spying, or surveillance of a private individual. As a verb, it describes covert observation or information-gathering, particularly when done without the knowledge or permission of the person being observed. The word carries a strong negative connotation because spying often involves secrecy, deception, invasion of privacy, or illegal access to information. It can also be used more broadly to describe suspicious or intrusive behavior, such as spying on a competitor's business. In journalism and history, the term is frequently associated with intelligence agencies, clandestine networks, and international conflict.

The present participle form is common in both British and US English. The phrase “spy on” is particularly frequent.
Spying turns ordinary curiosity into a hidden craft: every glance, conversation, or document may become part of an intelligence-gathering operation.

Etymology of spying
The word derives from the Old French espier, meaning “to watch” or “to observe,” and ultimately from Latin specere, “to look at.” The English verb spy developed in the Middle English period and initially referred to watching or examining closely, before acquiring its modern sense of secret observation. Related words include espionage, which refers to the organized activity of gathering secret information, and spyglass, an instrument originally used for viewing distant objects.
