-ology, -logy, -ologist, -logist

(Greek: a suffix meaning: to talk, to speak; a branch of knowledge; any science or academic field that ends in -ology which is a variant of -logy; a person who speaks in a certain manner; someone who deals with certain topics or subjects)

The word -ology is a back-formation from the names of certain disciplines. The -logy element basically means "the study of ____". Such words are formed from Greek or Latin roots with the terminal -logy derived from the Greek suffix -λογια (-logia), speaking, from λεγειν (legein), "to speak".

The suffix -ology is considered to be misleading sometimes as when the "o" is actually part of the word stem that receives the -logy ending; such as, bio + logy.

Through the years -ology and -logy have come to mean, "study of" or "science of" and either of these suffixes often utilize the form of -ologist, "one who (whatever the preceding element refers to)".

The examples shown in this unit represent just a small fraction of the many words that exist in various dictionaries.

geoarchaeology
The techniques of geology applied to archaeological issues; such as, dating methodology, mineral identification, soil and stratification analysis; the investigation of the relationship between archaeological and geological processes.

It is an ecological approach to archaeology with the goal of understanding the physical context of archaeological remains and the emphasis on the interrelationships among cultural and land systems.

geobiologist
Someone who studies the biosphere or who specializes in the study of the interdisciplinary field of scientific research that explores interactions between the biosphere, the lithosphere, and the atmosphere.
geobiology
1. The study of the biosphere.
2. An interdisciplinary field of scientific research that explores interactions between the biosphere and the lithosphere and/or the atmosphere.
3. The study of terrestrial life.
geochronologist
Someone who studies the chronology, or time periods, of the earth, as based on both absolute and relative methods of age determination.
geochronology
1. The chronology of the earth; that is, the measurement of geological time and the ordering of past geological events.
2. The time sequence of the earth’s history as governed by geological events.
3. The science of dating and the study of time in relation to the earth's history as revealed by geological data.
geocosmology
The study of the geological origin and history of the earth.
geohydrology
1. The scientific study of subsurface water; especially, the study of the geologic settings of underground water.
2. The branch of geology that studies the movement of subsurface water through rocks and the effect of moving water on rocks, including their erosion.

The term geohydrology is often used interchangeably with hydrogeology. Some make the minor distinction between hydrologists or engineers who are applying themselves to geology (geohydrology), and geologists applying themselves to hydrology (hydrogeology).

geologist (singular), geologists (plural)
A scientist who specializes in the study of the origin, composition, history, structure, and processes of the earth.

One geologist claimed that geologists go to rock'n'roll concerts for entertainment and when they relax, they do it in a rocking chair; but their favorite kind of transportation is a rocket.

geology
1. The study of the earth in terms of its development as a planet since its origin, including the history of its life forms, the materials of which it is made, the processes that affect these materials, and the products that are formed from them.
2. The science which includes the structure and mineral constitution of the globe; structural geology.
3. The study or science of the earth, its history, and its life as recorded in the rocks; includes the study of geologic features of an area; such as, the geometry of rock formations, weathering and erosion, and sedimentation.
geomorphologist
Someone who studies the surface configurations of the earth and the history of geologic activities as represented by such surface features.
geomorphology
1. The study of the classification, description, nature, origin, and development of present landforms and their relationships to underlying structures, and of the history of geologic changes as recorded by these surface features.
2. That branch of geology that studies the characteristics, processes that shape them, and configurations and evolutions of rocks and land forms.

Geomorphologists seek to understand landform history and dynamics, and predict future changes through a combination of field observations, physical experiments, and numerical modeling.

The discipline is practiced within geology, geography, archaeology, and civil and environmental engineering. Early studies in geomorphology are the foundations for pedology, one of two main branches of soil science.

Geomorphology is the science of landforms. It is the science that provides us with a closer look at the earth's surface and the processes that have formed them.

Although geomorphology is concerned with landforms that currently exist, past landforms and events must be examined in order to fully understand how they came about.

Although the term geomorphology is a relatively new term (1880's), the examination of the forces of nature that have impacted the earth's surface extends back into the days of early Greek and Roman philosophers; such as, Aristotle and Seneca.

Their writings included ideas on stream erosion, earthquakes, and other deformations. Though these early philosophers speculated on the ideas of landscape evolution, these processes and thoughts were not fully examined until just before the 1800's.

geopathology
1. The study of the peculiarities of disease in relation to topography, climate, food habits, etc., of various regions of the earth.
2. The science concerned with the harmful effects on the body of environment, topography, climate, food and water supplies, and ecological factors.
geotechnology
The application of scientific methods and engineering techniques to the exploitation and utilization of natural resources; such as, mineral resources.
geratology (s) (noun), geratologies (pl)
In biology, the study of the decline and senescence or old age of populations.
gerodontology
The study of dentistry in relation to the aging, aged, or elderly.
