-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.

ethnopharmacology, ethnopharmacological
1. The systematic study of the use of medicinal plants by specific cultural groups.
2. The study and use of plants, fungi, animals, microorganisms, and minerals; as well as, their biological and pharmacological applications.
3. A combination of the approaches of medical anthropology, phytotherapy, and pharmaceutical science, this discipline examines medicinal plants in indigenous cultures, their bioactive compounds, and the sustainable development and the production of nature-derived therapeutics.

Ethnopharmacologists are particularly concerned with local people’s rights to further use and develop their autochthonous (place of origin; indigenous, native) resources.

Today’s ethnopharmacological research embraces multidisciplinary efforts in the:

  • documentation of indigenous medical knowledge.
  • scientific study of indigenous medicines in order to contribute in the long-run to improved health care in the regions of the studies.
  • search for pharmacologically unique principles from existing indigenous remedies.
  • combinations of such diverse fields as anthropology, pharmacology, pharmacognosy, pharmaceutical biology, natural product chemistry, toxicology, clinical research, and plant physiology.

3. The study of the causes of diseases or medical disorders.

The word etiology is primarily used in medicine, where it refers to the science that deals with the causes or origins of diseases including the factors which produce or predispose toward a certain disease or disorder.

Today in medicine one often hears, or reads: "The etiology is unknown"; meaning: "We don't know the cause."

Aetiology is the preferred spelling in some countries, including the UK, whereas etiology, without an "a", is dominant in the United States.

etymologist (s), (noun), etymologists (pl)
A lexicographer who specializes in trying to reconstruct information about languages that are too old for any direct data can be known; since so many have no written records for examinations.

By comparing words in related languages, people may learn about their shared parent languages and in this way, some word roots have been found which can be traced all the way back to the origin of the Indo-European language family.

An etymologist is a scholar who knows the difference between an etymologist and an entomologist.

etymology (s) (noun), etymologies (pl)
1. The origin and historical development of a linguistic form as shown by determining its basic elements, the earliest known uses, and changes in form and meanings: Etymology is the science or the study of original vocabulary meanings.
2. Tracing the transmissions of words from one language to another and identifying their relationships in other languages, and reconstructing their ancestral forms when possible: The English language has borrowed many roots from Greek and Latin; so, one important aspect of historical linguistics involves the etymology of words that come from those classical languages as well as some other contributing sources; such as, French, German, Anglo-Saxon, Scandinavian, Indo-European, etc.

Through old texts and comparisons with other languages, etymology is an effort to reconstruct the history of words; when they entered a language, from what sources, and how their forms and meanings have changed.

etymythology (s) (noun), etymythologies (pl)
