词根词缀：-ology, -logy, -ologist, -logist

【来源及含义】Greek: a suffix meaning: to talk, to speak; a branch of knowledge; any science or academic field that ends in -ology which is a variant of -logy; a person who speaks in a certain manner; someone who deals with certain topics or subjects

【相关描述】The word -ology is a back-formation from the names of certain disciplines. The -logy element basically means "the study of ____". Such words are formed from Greek or Latin roots with the terminal -logy derived from the Greek suffix -λογια (-logia), speaking, from λεγειν (legein), "to speak".

The suffix -ology is considered to be misleading sometimes as when the "o" is actually part of the word stem that receives the -logy ending; such as, bio + logy.

Through the years -ology and -logy have come to mean, "study of" or "science of" and either of these suffixes often utilize the form of -ologist, "one who (whatever the preceding element refers to)".

The examples shown in this unit represent just a small fraction of the many words that exist in various dictionaries.

【来源及含义】Greek: said to be a stem for "all, every, whole", or "complete"; that is, a field of study in biology that refers to the whole set of omics including their -omics and -ome subfields in order to understand life as a holistic existence and organic beings as a whole

【相关描述】Bioinformatists and molecular biologists are thought to be among the first scientists to start to apply the -ome suffix in several scientific areas.

Bioinformatics is an information science that analyzes life processes using computational tools for solving biological problems and to give direction or an overview in biology.

Ome and omics are convenient ways to describe a holistic way of looking at complex systems. In the mid 1990's bioinformatists started realizing the convenience of -omics and used terms for many fields; such as, metabolome, textome, interactome, bacteriome, eukaryome, functome, patentome, neurome and so on.

Omics was coined by scientists to present the realization of the importance of information processing in biology that was proposed by many biologists and as such, it was made possible by the development of personal computers and personal computer operating systems; such as, Windows, Linux, and Apple.
