-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.

tropology (s) (noun), tropologies (pl)
1. The use of figurative language in speech or in writing.
2. A figure of speech in which words or phrases are used with a nonliteral or figurative meaning.
typology (s) (noun), typologies (pl)
1. A doctrine, or theory that things in the Christian dispensation are symbolized or prefigured by things in the Old Testament: The Greek words which help people understand typology come under a verbal root that means "to beat, to strike, or to smite".

Usually the New Testament uses typology as a method of interpreting the Old Testament without explicitly saying so.

Typology, a comparison stressing one point of similarity, helps people to see the New Testament person, event, or institution as the fulfillment of that which was only hinted at in the Old Testament.
