The English suffix -ology or -logy denotes a field of study or academic discipline, and -ologist describes a person who studies that field. However not every field or study or discipline is an '-ology', for instance the study of childbirth is midwifery and a practitioner is a midwife.
EtymologyThe word ology is a back-formation from the names of these disciplines. "-logy" 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), from λόγος (logos) and that from λέγω (lego), to speak. The word ology is thus misleading as the 'o' is actually part of the word stem that receives the -logy ending. For example, the bio part of biology stems from Greek βιος (bios), life. This is why some of the words do not end in -ology (such as mineralogy).
Other words ending in "ology"Not all words ending in -ology are ologies in the above sense. In some words such as tautology, philology and haplology, the -logy suffix is from the Greek λογος (logos), word, and may denote something related to speech or text. Also called Emology for a scientific name.
UsageAlthough technically incorrect, "-ology" is sometimes used to describe a subject rather than the study of it. Technology is a typical example. This usage is also widespread in medicine; for example, pathology is often used for specific disease ("We haven't found the pathology yet").
"Ology" can be appended to any word, humorously, when describing its study; such as beer-ology or Wiki-ology. As with other Classical compounds, adding "ology" to a Latin or Greek based prefix may be used to lend grandeur or the impression of scientific rigor to humble pursuits, as in cosmetology (hairdressing) or cynology (dog training.)
There are a few irregular exceptions to the ending "-ologist"; for example theology/theologian.
They can also refer to the 'Ology series of books, fictional encyclopedias, currently including Dragonology: The Complete Book of Dragons, Egyptology: Search for the Tomb of Osiris, Wizardology: The Secrets of Merlin, Pirateology: A Pirate Hunter's Companion, and Mythology: Greek Gods, Heroes, & Monsters.
