What does the suffix -lith refer to?

The suffix -lith refers specifically to "stone." This term comes from the Greek word "lithos," meaning stone. In medical terminology, it is commonly used to denote types of stones within the body, such as in the words "urolith" (a stone in the urinary tract) or "cholelith" (a gallstone). This suffix directly signifies the substance itself, which is why it is accurate to say that -lith describes a stone.

The other terms, while related, convey different meanings. One describes a condition associated with stones, another indicates the study of a subject, and the last refers to a person engaging in study, which do not align with the straightforward concept of a stone that -lith embodies. Understanding the precise definition of suffixes is crucial in medical terminology as it helps in deciphering the meanings of complex medical terms.
