1797, "the science of phenomena, as distinct from that of being;" 1840 as "a description or history of phenomena," the latter sense from German Phänomenologie, used as the title of the fourth part of the "Neues Organon" of German physicist Johann Heinrich Lambert (1728-1777), coined from Greek phainomenon (see phenomenon) + -logia (see -logy). Psychological sense, especially in Gestalt theory, is from 1930. Related: Phenomenological; phenomenologically.
1650s, "the study of the soul," from Modern Latin psychologia, probably coined mid-16c. in Germany by Melanchthon from Latinized form of Greek psykhē "breath, spirit, soul" (see psyche) + logia "study of" (see -logy). The meaning "science or study of the phenomena of the mind" is attested by 1748, in reference to Christian Wolff's "Psychologia empirica" (1732). The modern behavioral sciences sense is from the early 1890s.
suffix indicating state, condition, or quality; also activity or the result of it (as in victory, history, etc.), via Anglo-French and Old French -é, from Latin -ia, Greek -ia, from PIE *-a-, suffix forming abstract or collective nouns. It is etymologically identical with -ia and the second element in -cy, -ery, -logy, etc.
word-forming element indicating "branch of knowledge, science," now the usual form of -logy. Originally used c. 1800 in nonce formations (commonsensology, etc.), it gained legitimacy by influence of the proper formation in geology, mythology, etc., where the -o- is a stem vowel in the previous element.
The second element is prop[erly] -logy (-logue, etc.), the -o- belonging to the preceding element; but the accent makes the apparent element in E[nglish] to be -ology, which is hence often used as an independent word. [Century Dictionary]
"the study of rivers," 1829, in "POTAMOLOGY : a Tabular Description of the Principal Rivers throughout the World,—their Rise, Course, Cities, &c., Tributary Streams, Length and Outfall into Oceans, Seas, or Lakes," compiled and printed by George Smallfield, from potamo- + -logy. Related: Potamological.
POTAMOLOGY—what is that? Why the science of Rivers, to be sure ; and a very good science it is ; and a very good word it is, to designate that science, coined out of sterling Greek, its two etymons flowing harmoniously together into a continued stream of sound, and well deserving to become a current expression. [The Monthly Repository and Review, January, 1829]
mid-14c., "the science of religion, study of God and his relationship to humanity," from Old French theologie "philosophical study of Christian doctrine; Scripture" (14c.), from Latin theologia, from Greek theologia "an account of the gods," from theologos "one discoursing on the gods," from theos "god" (from PIE root *dhes-, forming words for religious concepts) + -logos "treating of" (see -logy). Meaning "a particular system of theology" is from 1660s.
Theology moves back and forth between two poles, the eternal truth of its foundations and the temporal situation in which the eternal truth must be received. [Paul Tillich, "Systematic Theology," 1951]
Who hates science, but does not love wisdom the lesson on that account, is named a misologist. Misology commonly arises from a want of scientific knowledge, and from a certain sort of vanity therewith conjoined. And sometimes those, who at first cultivated the sciences with great diligence and success, but in the end found no satisfaction in all their knowledge, fall into the fault of misology. [John Richardson, introduction to English translation of Kant's "Knowledge," 1819]
1650s, "general science or theory of the material universe as an ordered whole," from Modern Latin cosmologia, from Greek kosmos (see cosmos) + -logia "discourse" (see -logy). By 1753 as "the branch of metaphysics which discusses the ultimate philosophical problems relating to the existence of the universe." Related: Cosmologist.
They cannot scare me with their empty spaces
Between stars—on stars where no human race is.
I have it in me so much nearer home
To scare myself with my own desert places.
[Robert Frost, from "Desert Places," 1936]
1770, from German Terminologie, a hybrid coined by Christian Gottfried Schütz (1747-1832), professor of poetry and rhetoric at Jena, from Medieval Latin terminus "word, expression" (see terminus) + Greek -logia "a dealing with, a speaking of" (see -logy). Related: Terminological.
Decandolle and others use the term Glossology instead of Terminology, to avoid the blemish of a word compounded of two parts taken from different languages. The convenience of treating the termination ology (and a few other parts of compounds) as not restricted to Greek combinations, is so great, that I shall venture, in these cases, to disregard this philological scruple. [William Whewell, "The Philosophy of the Inductive Sciences," 1847]
