-->The [[suffix]] '''ology''' is commonly used in the English language to denote a field of study. The ''ology'' ending is a combination of the letter ''o'' plus ''[[-logy|logy]]'' in which the letter ''o'' is used as an [[thematic vowel|interconsonantal]] letter which, for [[phonological]] reasons, precedes the [[morpheme]] suffix ''[[-logy|logy]]''.<ref name="etymonline">{{cite web|last1=Harper|first1=Douglas|title=-ology|url=http://www.etymonline.com/index.php?term=-ology&allowed_in_frame=0|website=Online Etymology Dictionary|access-date=7 May 2016}}</ref> ''Logy'' is a [[suffix]] in the English language, used with words originally adapted from [[Ancient Greek]] ending in {{lang|grc|[[wiktionary:-λογία|-λογία]]}} (''-logia'').<ref>List of ancient Greek words ending in [https://www.perseus.tufts.edu/hopper/resolveform?type=end&lookup=logia&lang=greek -λογία] on [[Perseus Project|Perseus]]</ref>
English names for fields of study are usually created by taking a [[Root (linguistics)|root]] (the subject of the study) and appending the suffix ''logy'' to it with the interconsonantal ''o'' placed in between (with an exception explained below). For example, the word [[dermatology]] comes from the root ''dermato'' plus ''logy''.<ref>{{cite web|title=dermatology|url=http://www.etymonline.com/index.php?term=dermatology|website=Online Etymology Dictionary|access-date=23 July 2016}}</ref> Sometimes, an [[Epenthesis|excrescence]], the addition of a consonant, must be added to avoid poor construction of words.
There are additional uses for the suffix such as to describe a subject rather than the study of it (e.g. [[technology]]). The suffix is often humorously appended to other English words to create [[nonce words]]. For example, ''stupidology'' would refer to the study of stupidity; ''beerology'' would refer to the study of beer.<ref name="etymonline" />
Not all scientific studies are suffixed with ''ology''. When the root word ends with the letter "L" or a vowel, exceptions occur. For example, the study of [[mammals]] would take the root word ''mammal'' and append ''ology'' to it resulting in ''mammalology'' but because of its final letter being an "L", it instead creates ''[[mammalogy]]''. There are exceptions for this exception too. For example, the word [[angelology]] with the root word ''angel'', ends in an "L" but is not spelt ''angelogy'' as according to the "L" rule.<ref>Eric Partridge, ''Origins'', 2nd edition,New York, Macmillan, 1959</ref><ref>[http://words-ending-in-ogy.wordover.com/e/ Words Ending In ogy : Words Ending With ogy<!-- Bot generated title -->]</ref>
The terminal ''-logy'' is used to denote a discipline. These terms often utilize the suffix ''-logist'' or ''-ologist'' to describe one who studies the topic. In this case, the suffix ''ology'' would be replaced with ''ologist''. For example, one who studies ''[[biology]]'' is called a ''[[biologist]]''.
This list of words contains all words that end in ''ology''. It includes words that denote a field of study and those that do not, as well as common misspelled words which do not end in ''ology'' but are often written as such.
