What does the suffix -sis denote?

The suffix -sis is used to indicate a state of or condition. It is derived from Greek and commonly appears in medical terminology to describe various conditions, processes, or states associated with health and disease. For example, in terms like "diagnosis" or "neurosis," the suffix helps to convey the state or condition being referenced.

While other suffixes in medical terminology serve different purposes (like indicating abnormal conditions, growth, or control), -sis specifically highlights a state or condition associated with a particular process or phenomenon. The understanding of such suffixes is crucial for comprehending medical language as they provide insight into the nature of the term being used.
