What does snooper mean?
A snooper is someone who secretly watches, listens, or searches for information, usually concerning another person's private affairs. The word often carries a negative or comic connotation because snooping suggests curiosity and intrusion: a snooper wants to know what is happening beyond the boundaries of their own business or responsibility. It may describe a casual observer, such as a nosy neighbour, or an organized investigator, such as a government or corporate spy, depending on context. “Snooper” is related to the verb “snoop,” which means to look or listen furtively. In journalism and historical writing, the term can refer to people employed to monitor others, including political or commercial operatives. Unlike the more general word “spy,” “snooper” often emphasizes clandestine observation rather than espionage in the strict sense of gathering intelligence for a government. The expression is established in both British and American English.

Where does snooper come from?
“Snooper” is an agent noun formed from the English verb “snoop.” The verb dates from the early 19th century, but its ultimate origin is uncertain; it has sometimes been associated with the Dutch word snoepen, meaning to snoop or sneak about. The derivative “snooper” subsequently developed the specific sense of a person who engages in furtive observation.
