surveil
Keep under observation
To surveil is to watch someone or something closely, typically for purposes of gathering intelligence or monitoring behavior.
The word is a back-formation from surveillance, used when you need a verb: Federal agents surveilled the suspect for months.
It sounds bureaucratic and appears mainly in law enforcement, intelligence, and journalism contexts.
