-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.

acridology (s) (noun)
The scientific study of grasshoppers, locusts, and crickets.

Extending her abdomen to about twice its normal length, a female locust deposits a pod of some 70 rice-size eggs four inches deep in moist sand.

Sensors at the end of her tail test moisture, salinity, temperature, and the softness of the ground to ensure that conditions are proper for laying her eggs.

To hatch, the eggs must absorb their weight in water, ideally in the first five days. During the last weeks of her four-month life, the gregarious female lays three times, usually a total of about 200 eggs.

Big-eyed hoppers hatch from the warm sands. The locusts promptly shed their natal skins, turn dark after about two hours in the sun, and within a few days they begin to move off in dense swarms.
