What does surveillant mean?
Surveillant means watchful, monitoring, or given to observing others, and it often carries the implication that this observation is systematic, institutional, or politically charged. The adjective is especially common in phrases such as “surveillant state,” where it describes a government or other authority that closely monitors the behavior of citizens. It can also characterize a person, presence, or system that watches attentively. As a noun, a surveillant is an observer or agent whose purpose is to watch and report. The word has a formal and somewhat austere register and is chiefly used in American English. Unlike surveillance, which names the activity or system of monitoring, surveillant usually focuses on the watchful quality or the person performing that role.
Watchful or observant, especially with regard to security, policing, or political monitoring.
"The government resisted calls for a more surveillant system."
Chiefly American English; often formal and politically critical.
A person or agent whose role is to watch, monitor, or report on others.
"The agent remained a discreet surveillant outside the building."
Relatively uncommon compared with the adjective.
The plural is used when referring to multiple observers or monitoring agents.
"Several surveillants observed the perimeter."
Surveillant turns the idea of watching into a political condition: a surveillant state watches not only its enemies but often its own people.

Where does surveillant come from?
The word comes from French, where surveillant means “watching” or “a watcher,” and is formed from surveiller, “to watch,” with the suffix -ant. English borrowed it in the early 20th century, initially in political and legal contexts. Its association with states and institutions reflects the French expression État surveillant, “surveillant state.”
