-ology, -logy, -ologist, -logist
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 subspecialty of obstetrics concerned with the care of the mother and fetus at higher-than-normal risk for complications: Since Kitty loved babies and little children she decided to study
perinatology and work as a doctor later on.

The comparable area of pediatrics is "neonatology". A high-risk baby might be cared for by a "perinatologist" before birth and by a "neonatologist" after birth.
