Etymology: "Ological" is not a root word but a suffix, "-ology," made into an adjective by adding "-ical." The suffix comes from Greek "logia," a combining form of "logos," meaning "word," "speech," or "reason," which gave English a large family of names for fields of study, such as "biology" and "geology." Strictly speaking, "-ology" marks a discipline and "-ological" describes things belonging to it. The joking sense is the surprising part. Writers started using "-ological" as a stand-in for any field of study, real or invented, so that a phrase like "the whole ological mess" could refer to a jumble of specialist terms without naming one. The word is often used this way in informal speech, where the speaker is gesturing at expertise rather than claiming a particular discipline. Its exact date of entry into English and the first writer to use it in this joking way are not something I can confirm, so the record of its playful use is best understood as a pattern in everyday speech rather than a single documented coinage.
