What does deconditioned mean?
Deconditioned describes something whose conditioning has been removed, reversed, or allowed to fade. In psychology and behavioural science, it can mean that a learned response—such as a fear elicited by a particular sound—has been extinguished through deliberate procedures. In medicine, rehabilitation, and physical conditioning, it more often describes a person who has become less fit because of inactivity or illness. As an adjective, deconditioned places emphasis on the resulting state; as the past tense or past participle of decondition, it describes an action or process that brought that state about. The word is more technical than everyday and should not be confused with unconditioned, which means never having been conditioned in the first place. Its usefulness lies in distinguishing active removal of learned or physical conditioning from a simple absence of training: deconditioning means that something once acquired has been lost or undone.
Having had conditioning removed or reversed; having lost a learned response or physical conditioning.
"The therapist helped the patient become less fearful of the remembered sound."
The physical sense is common in clinical and rehabilitation contexts, while the behavioural sense is chiefly used in psychology and conditioning experiments.
To remove or reverse conditioning, thereby weakening or extinguishing a learned response.
"The researchers deconditioned the animals by gradually removing the stimulus associated with the response."
Usually transitive and technical. It is more specific than simply ceasing to train someone or something.
Sometimes progress begins with unlearning: deconditioned marks a response stripped of the learned trigger that once set it in motion.

Where does deconditioned come from?
Deconditioned is a modern English formation built from de-, meaning reversal or removal, condition, and the suffix -ed. Condition came through Middle English from Latin conditio, meaning a stipulation or agreement, and is ultimately connected with Latin condere, meaning to establish or agree. Related English forms such as conditional, unconditional, and unconditionally continue this same etymological family.
