Abstract: Lettered-words have been included into “Acronyms and Words Beginning with Greek or Latin Letters” in the Contemporary Chinese Dictionary(the third edition) since 1996. Till now, the appendix has been revised three times. In this paper, we analyze the inclusion and revision of lettered-words from their number, category and explanation, and then further discuss the necessity and method of lettered-words standardization.
