漢： -logy是最常用的術(shù)語(yǔ)後綴之一。正如多數(shù)術(shù)語(yǔ)詞綴一樣，它來(lái)源於古希臘語(yǔ)。作爲(wèi)原生後綴，-logy主要加在希臘名詞詞根（或希臘術(shù)語(yǔ)前綴）後麪。有時(shí)它需要依靠連接字母-o-幫助搆詞。-logy的主要意思是the doctrine,study or science of ～（...論，...學(xué)，...科）。有時(shí)表示它在希臘文中的原意the speech or discussion of ～(...的言語(yǔ)）。順便指出，與-logy相對(duì)應(yīng)的表示“...學(xué)的”與“...者”的後綴分別是-logical與-logist。-logy 是現(xiàn)代英語(yǔ)中也是被用作派生後綴，加在名詞上，搆成科學(xué)術(shù)語(yǔ)。此外，注意log意爲(wèi)“speech”

英：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.
