-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)".

2. Tracing the transmissions of words from one language to another and identifying their relationships in other languages, and reconstructing their ancestral forms when possible: The English language has borrowed many roots from Greek and Latin; so, one important aspect of historical linguistics involves the etymology of words that come from those classical languages as well as some other contributing sources; such as, French, German, Anglo-Saxon, Scandinavian, Indo-European, etc.
Through old texts and comparisons with other languages, etymology is an effort to reconstruct the history of words; when they entered a language, from what sources, and how their forms and meanings have changed.
