What does operant mean?
Operant is a formal word meaning operating, functioning, or having the capacity to produce an effect. It can describe a person, institution, mechanism, or system that is active and effective, although it is much less common than working, functional, or operational in everyday speech. In psychology, operant has a more specialized meaning: it refers to behavior that is learned or modified according to its consequences. A rewarded operant becomes more likely to occur, while one followed by an unpleasant consequence may become less likely. The term is central to operant conditioning, a framework associated with B. F. Skinner. In general contexts, operant conveys precision and technicality rather than warmth, so it is especially suitable for scientific, administrative, and systems-oriented writing.
Operating or functioning; producing an effect.
"The restoration process remained operant throughout the year."
Formal and relatively uncommon; operational is often more natural in modern English.
A person, thing, or action that operates; in psychology, a behavior whose occurrence is affected by the consequence that follows it.

The psychological sense is technical and normally appears in discussion of behavior, learning, reinforcement, and operant conditioning.
Pluralized when referring to multiple operating persons or things, or to multiple behaviors affected by consequences.

In psychology, an operant learns through consequences: behavior that is rewarded is more likely to return.

Etymology of operant
Operant comes from the Latin present participle operans, meaning “operating” or “doing,” from operari, “to work” or “to operate.” English borrowed the term in the 19th century for an operating person or thing. Its later psychological sense developed in the 20th century from broader behavioral terminology, especially through the study of operant conditioning.
