-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.

Someone who investigates the relations between the sun, moon, and stars; as well as, their influences on the weather of the earth.

2. The investigation of the (alleged) influence upon the weather, climate, etc. of planetary and stellar phenomena; such as, sun-spots, phases of the moon, comets, meteors, and planetary conjunctions.

This was a branch of an older natural astrology; and the term is often applied to a pretended prognostication of the weather, which is no better than modern "astrology".
