-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.

A few humorous examples of folk etymology

The word woman is derived from woe- + man; and so, "a bringer of woe".
The origin of virgin, comes from vir, Latin for "man", and gin, "a trap" and so a virgin is "a mantrap" or a "trapper of men".

forensic entomology
The examination of insects in, on, and around human remains to assist in determining the time or location of death.

Medicolegal forensic entomology includes arthropod involvement (mostly necrophagous or corpse-eating) involving events such as murder, suicide and rape, but also includes physical abuse and contraband trafficking.

In murder investigations, it is concerned with where and when insects lay eggs; and in what order they appear in dead bodies. This can be helpful in determining the time or post mortem interval and location of the death being investigated.

forensic meteorology
The process of reconstructing weather events for a certain location.

This is done by acquiring local weather reports, radar and satellite images, and eyewitness accounts.

Forensic meteorology is most often used in court cases for use by insurance companies or for a murder investigation.

forensic pathology
A branch of medicine concerned with determining the cause of deaths usually for civil or criminal law cases.

The forensic pathologist performs autopsies to determine the cause of a death; such as, examining a bullet wound to the head, exsanguination, strangulation, etc. and the manner of a death (including homicide, accident, natural, or suicide).

Forensic pathologists also work closely with the coroner (England and Wales) or medical examiner (United States). The examination of dead bodies (autopsy or post mortem) is a subset of anatomical pathology.

Forensic pathologists are often also known as forensic medical examiners or police surgeons.
