De formation refers to a state of being malformed or deformed. The opposite of this would be a state of being perfectly formed or well-shaped. Some antonyms for de formation might include "normal," "healthy," "undamaged," "developed," "flawless," or "well-proportioned." These words suggest a state of physical or structural integrity, and can be contrasted with the concept of de formation, which implies a deviation from an ideal or expected form. Within the realm of medical or biological research, antonyms for de formation may be especially relevant, as scientists seek to understand how to prevent or correct physical deformities in living organisms.
