Which suffix indicates a practice or a process?

The suffix that indicates a practice or a process is -practic. This suffix is derived from the root "practic," which relates to doing or performing a particular activity. In medical terminology, it is often associated with specific fields of practice, implying a systematic method or procedural approach to care or treatment. For instance, in words like "chiropractic" or "podiatric," -practic conveys the idea of a practiced method within those specific areas of healthcare.

The other suffixes provided serve different purposes: -logy refers to the study of a subject (like biology or cardiology), -pathy denotes a disease or disorder (as in homeopathy or neuropathy), and -metry relates to measurement (as seen in terms like optometry or telemetry). Each of these forms has its own distinct meaning that aligns with a specific aspect of the medical field, but none directly convey the concept of practice or process as effectively as -practic does.
