【来源及含义】Greek: jaw

【相关描述】The jaw is the name applied to the bones which contain the teeth.

The two upper jaw-bones, the maxillae, are firmly attached to the other bones of the face.

The lower jaw, the mandible, is shaped in a form similar to that of a horseshoe, and, after the first year of life, it consists of a single bone.

It forms a hinge-joint with the squamous part (thin, plate-like section) of the temporal bone, immediately in front of the ear.

Both the upper and the lower jaw-bones include deep sockets known as alveoli, which contain the roots of the teeth.

【来源及含义】Greek: bath, bathing

【相关描述】A discussion about the above words appeared in the April 19, 1993, issue of The Christian Science Monitor in an article, "Dictionary Service Answers Questions About Words" (page 14) that described an organization known as "OWLS" [Oxford Word and Language Service]. One writer wrote, "Please can you tell me the word for a person who drinks their [sic] own bath water, as opposed to one who drinks another's bath water?" These words do not exist in any dictionary. Part of the OWLS' reply read: "As the concept is not central to European civilization, I am not surprised that it has failed to find a place in dictionaries. If words for this are needed in the future, then autoloutrophilist and alloloutrophilist are waiting in the wings for their brief flash of celebrity."

【来源及含义】Greek: sea, ocean

【相关描述】Traditionally, there are five oceans: the Atlantic, the Pacific, the Indian, the Arctic, and the Antarctic. The Antarctic Ocean, lacking any precise natural boundaries, is sometimes considered an extension of the Atlantic, the Pacific, and the Indian oceans.

The adjacent bodies of salt water and various subdivisions of the oceans are generally known as seas, but local usage may also sanction such terms as gulfs, bays, channels, and straits; designations that are sometimes used interchangeably.
