-logy versus -ology
In English names for fields of study, the suffix -logy is most frequently found preceded by the vowel o so the word ends in -ology. In traditional English grammar, the -o- in -ology is considered part of the suffix -logy. This is because the -o- is not part of the suffix in the original Greek names for fields of study: In these Greek words, the root is always a noun and -o- is the combining vowel for all declensions of Greek nouns. However, when new names for fields of study have been coined in modern English, the formations ending in -logy almost invariably follow the Greek model by adding an -o-, even though there is no grammatical necessity in English. There are at least »22 exceptions: analogy, dekalogy, disanalogy, genealogy, genethlialogy, herbalogy (a variant of herbology), »idealogy, mammalogy, mineralogy, paralogy, »pentalogy, petralogy (a variant of petrology), tetralogy; »elogy; antilogy, »festilogy, trilogy; »palillogy, »pyroballogy; »dyslogy; eulogy; and brachylogy."-logy."

Additional usage as a suffix
Per metonymy, words ending in -logy are sometimes used to describe a subject rather than the study of it (e.g. technology). This usage is particularly widespread in medicine; for example, pathology is often used simply to refer to "the study of a disease" but to refer to "the disease" itself (e.g. "We haven't found the pathology yet").
Books, journals and treatises about a subject also often bear the name of this subject (e. g. Ecology (journal)).
When appended to other English words, the suffix can also be used humorously to create nonce words (e.g. beerology as "the study of beer", Wikiology as "the study of Wikipedia"). As with other classical compounds, adding the suffix to a initial word-stem derived from Greek or Latin may be used to lend grandeur or the impression of scientific rigor to humble pursuits, as in cosmetology ("the study of beauty treatment") or cynology ("the study of dog training").
Additional usage as a substantive
When used as a proper noun, Ology can refer to a particular series of fantasy books and fictional encyclopedias. These currently include , , , , and .
