What does '-practic' imply in medical terminology?

The suffix '-practic' in medical terminology is derived from the Greek word "praktikos," which means 'to do' or 'to practice.' In the context of medical terminology, it pertains specifically to the act of practice or a method of performing a procedure. This is evident in words like "therapeutic" or "practicable," which incorporate this suffix to convey concepts related to practical application or action.

While knowledge, understanding, and diagnosis are important aspects of medical practice, they are represented by different roots or suffixes in medical terminology. Knowledge can relate to terms like 'cognition' or 'sci,' while understanding may involve terms derived from 'comprehensio.' Diagnosis is a process of identifying a disease or condition, typically represented by the root 'gnosis.' Thus, '-practic' distinctly emphasizes the notion of practice, making it the correct answer in this context.
