-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.

1. A branch of physiology concerned with the structure and function of tissues.
2. The microscopic study of tissues in relation to their functions.
historical geologists
Geologists who divide all time since the formation of the earliest known rocks (about four billion years ago) into four major divisions: Precambrian, Paleozoic, Mesozoic, and Cenozoic eras.

Each era, except the Cenozoic, ended with profound changes in the disposition of the earth's continents and mountains and was characterized by the emergence of new forms of life.

Broad cyclical patterns, which run through all historical geology, include a period of mountain and continent building followed by one of erosion and, and then by a new period of elevation.

historiology (s) (noun), historiologies (pl)
1. The knowledge or study of events from the past.
2. A discourse or science of chronological records or situations that occurred in the past.
hodology (s) (noun), hodologies (pl)
1. The scientific study of tracts or pathways in the central nervous system.
2. The study of pathways: in brain physiology, it is the study of the interconnections of brain cells; in philosophy, it is the study of interconnected ideas; in geography, it is the study of paths.
hologyny (s) (noun), hologynies (pl)
Characteristics that are manifested by or existing only in females.
A system of medical treatment based on the use of small quantities of remedies that in massive doses produce effects similar to those of the disease being treated.

Homeopathy, historical background

Homeopathy was invented by the German physician Samuel Hahnemann (1755-1843) in the late 18th and early 19th centuries. It was both refined and popularized by the American physician James Tyler Kent.

Homeopathy is based on the theory that each naturally occurring element, plant, and mineral compound will, when ingested or applied, result in certain symptoms. Hahnemann believed that, by diluting these substances in a standardized manner, one could reach the true essence of that substance. Hahnemann described this process of dilution as "potentizing" (German: potenziert) the substance. These dilute amounts could then be used to treat the very symptoms they were known to produce.

Hahnemann and his students approached their treatments in a holistic way, meaning that the whole of the body and spirit is dealt with, not just the localised disease. Hahnemann himself spent extended periods of time with his patients, asking them questions that dealt not only with their particular symptoms or illness, but also with the details of their daily lives.

It is also suggested that the gentle approach of homeopathy was a reaction to the violent forms of medicine of the day, which included techniques such as bleeding.

homology (hoh MOL uh jee)
1. Similar characteristics in two animals that are a product of descent from a common ancestor rather than a product of a similar environment.
2. The correspondence of a part or organ of one animal with a similar part or organ of another one, determined by agreement in derivation and development from a like primitive origin, as the foreleg of a quadruped, the wing of a bird, and the pectoral fin of a fish.
3. In chemistry, a similarity in compounds having the same fundamental structure but differing in constituents by a regular succession of changes; such as, the alcohols.
1. Clinical endocrinology or the study of hormones, the endocrine system, and their role in the physiology of the body.
2. A medical specialty concerned with the diagnosis and treatment of disorders of the endocrine system.
1. Someone who studies the science of measuring time.
2. Someone skilled in making clocks and watches.
horology (s) (noun), horologies (pl)
1. The scientific subject area of how time is measured: Because Timothy was very interested in old watches, and had a collection of them, he bought a book on horology to find out more about years, months, days, hours, minutes, etc.
2. The art of making timekeeping instruments; such as, clocks and sundials: Since she was a little girl, Tina was fascinated by old pocket watches and so she decided to study horology and learn more about how time can be determined.
