Which suffix refers to movement?

The suffix that refers to movement is -kinesia. This term is derived from the Greek word 'kinesis', which means movement or motion. In medical terminology, it is often used in various contexts to describe different types or aspects of bodily movement. For example, "bradykinesia" refers to slow movement, which is a common characteristic observed in conditions like Parkinson's disease.

The other suffixes do not pertain to movement. The suffix -itis refers to inflammation, commonly used in terms like arthritis (inflammation of the joints). The suffix -lepsy relates to seizures, as seen in epilepsy, while -lith refers to stones or calculi in the body, such as in cholelithiasis (gallstones). Each of these terms serves a specific purpose in medical language but does not convey the concept of movement like -kinesia does.
