What does speleology mean?
Speleology is the study of caves and the systems connected with them. It is a broad field that can include the geology of cave formations, the biology of cave-dwelling organisms, the chemistry of groundwater, and the archaeological or historical evidence preserved underground. The term is also used for the practical activity of exploring and investigating caves, particularly when this is done for scientific purposes. Speleologists may measure passages, examine mineral deposits, map underground systems, study bats or other adapted organisms, and investigate how caves have been used by people. Although caving is the usual word for the recreational pursuit of entering caves, speleology more strongly suggests a scientific or organized approach. The word is useful because it identifies a distinctive field that brings together earth science, biology, archaeology, and exploration.
The scientific study of caves, including their formation, geology, ecology, and history.
"The paper made an important contribution to speleology through its analysis of an unexplored cave system."
The term is especially common in academic, scientific, and specialist contexts.
The exploration and investigation of caves, particularly as an organized activity.
"They spent the summer conducting speleology in the limestone regions of the north."
For the general recreational activity of visiting and exploring caves, caving is more usual.
This plural is rare in modern usage; speleology is normally treated as an uncountable field or activity.
"The histories of major speleologies have been documented in regional cave surveys."
Speleology sits at the meeting point of geology, biology, archaeology, and exploration: a single cave can reveal stories about rocks, ecosystems, climate, and human history.

Where does speleology come from?
Speleology comes from the Greek spēlaion, meaning “cave” or “cavern,” combined with the Greek-derived suffix -logy, meaning “study of.” The compound was formed in the late 19th century as a specialized scientific term. It belongs to a family of words connected with the Greek root for a cave, including speleothem, a feature formed in a cave. The related English forms speleologist and speleological developed from the same scientific terminology.
