A CIA operative is a person employed by the Central Intelligence Agency (CIA) to carry out intelligence-related activities. The term 'SPOOK' (5 letters) is a slang term for a SPY, and 'AGENT' (5 letters) is another word for a person who works for an organization to carry out specific tasks. A 'SPY' (3 letters) is someone who secretly collects information about an enemy or competitor, while an 'agt' (3 letters) is a shortened version of the word 'AGENT'. Finally, a 'MOLE' (4 letters) is a person who works as a double AGENT, infiltrating an organization in order to gain information. All of these terms can be used to describe a CIA operative.
