【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：serv- (slave)

【来源及含义】Latin: servire, to serve, to be a slave; slave; slavery

【相关描述】From Latin servire, to be a slave, to serve; from servus, slave, which is an Etruscan loan word. Of course, the modern use of "serve" has gone beyond the "slavery" aspect, but we are considering the etymology of the words which apparently came from the original idea of "slavery".

This Latin serv- is not related to another serv-, -serve which means "to save, to preserve".
