【相关描述】The Roman god of sleep is Somnus; so, when we are sleepy, we are "somnolent". Sleep walking is "somnambulism" which in Latin means exactly the same thing; that is, "sleepwalking".

The son of Somnus is Morpheus, the god of dreams, indicating that sleep gives birth to dreams. Morpheus goes back through Latin to the Greek word for "form" or "shape" because dreams are forms and shapes developed in the mind while sleeping.

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.
