What is the prefix meaning 'soft'?

The prefix that means 'soft' is represented by the suffix "-malacia." This term is derived from the Greek word "malakos," which means soft. In medical terminology, it is often used to describe conditions that involve the softening of tissues. For example, osteomalacia refers to the softening of the bones, typically due to a deficiency of vitamin D. Understanding this prefix is important for interpreting medical terms related to tissue conditions and diseases.

The other options represent different concepts: "-itis" refers to inflammation, "-plasty" indicates surgical repair or reconstruction, and "-pathy" denotes disease or disorder. Each of these suffixes conveys particular medical meanings that do not relate to the concept of softness.
