What does the suffix "-sis" mean?

The suffix "-sis" is used in medical terminology to denote a state, condition, or process. When you see "-sis" at the end of a medical term, it typically refers to the condition or state related to the root word it accompanies. For example, "neurosis" refers to a state related to the nervous system, and "hypnosis" refers to a state of sleep or trance.

This usage underlines how medical terminology often conveys specific meanings through the combination of roots, prefixes, and suffixes. Understanding "sis" as indicative of a condition or state is essential for accurately interpreting various medical terms and their implications in health contexts.
