“物曰东西”虽然由来已久,但“东西”一词的起源却一直没有有理而且有据的说法。本文指出:常见于五代两宋的“动使”一词与“东西”词义相近,读音相仿,兴替时间相接,很可能是“东西”一词的先源。 Although things have been around for a long time, the origin of the word “things” has never been justified and well-founded. This paper points out that the term “moving angel” which is common in the Five Dynasties and the Two Songs is similar to the meaning of “east and west ” and its pronunciation is similar.
