* "De-" is often a prefix meaning "away from," "opposite of," or "undoing." While it's present in "deformity," it's not acting as a distinct prefix.
* "-ity" is a common suffix indicating a state or condition. However, in "deformity," it's part of the root word "form," which itself means "shape" or "structure."
Therefore, "deformity" is considered a single word with no identifiable separate prefix and suffix.
It's a combination of the prefix "de-" and the root word "form," followed by the suffix "-ity," all working together to form a single concept.
