What does nonoperative mean?
Nonoperative is an adjective meaning that something is not functioning, operating, effective, or in force. Its meaning depends on context: in medicine, a nonoperative injury or treatment is one managed without surgery; in engineering or general use, a nonoperative device or system is not working; and in legal writing, a nonoperative provision or agreement is not currently in force. The word is often more specific than the broad negative "not working," because it can imply either the absence of an expected function or the absence of a desired effect. It is also common in phrases such as nonoperative management and nonoperative treatment. Because the term appears chiefly in technical and formal contexts, nonoperative generally sounds more precise and professional than casual alternatives such as "not working."

Where does nonoperative come from?
Nonoperative was formed in English by combining the prefix non-, meaning "not," with operative, a word derived from Latin through French. Operative ultimately comes from Latin operari, meaning "to work," the same root found in operate, operation, and operator. The same Latin verb also underlies cooperate, although its meaning developed from the idea of working together.
