词根词缀：inter-, intero-
【来源及含义】Latin: between; among, mutually, together; on the inside, internal
【相关描述】Although abstracted from the many compounds in which it entered English, the form inter- was not generally considered a living prefix in English until the 1400s.
During the later period of Middle English many words borrowed in the Old and Middle French forms entre-, enter- began to be consciously respelled with Latin inter-; although vestiges of the older French borrowings are found in entertain and enterprise.
The living prefix inter- is now freely added to almost any element in English to create such formations with the meaning of "between" and "among". The words formed by intra- are closely related to this inter- prefix; in fact, they both apparently came from the same Latin source.

While some words are borrowings from Medieval and even Late Latin, few if any come from Classical Latin.

词根词缀：loutro-, loutr-
【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."
