段玉裁《说文解字.叙》注中所谓的古字,分为两种情况:一是段玉裁对许慎的《叙》本身用字所作的注解(20条);二是段玉裁在注解过程中所使用的文字(16条)。段氏在著述中与许慎保持一致,尽量用古字进行注解,或指出某字“只作某”、“当作某”,即为古字。这反映了段玉裁的用字观。 Duan Yucai “Explain Word. Syria” Note in the so-called ancient word, divided into two situations: First, Duan Yu cut Xushen “Syria” itself made by the word notes (20); second paragraph Jade cut in the annotation process used in the text (16). Duan in the book with Xu Shen consistent, try to use ancient characters for annotation, or pointed out that the word “only for a”, “as a”, is the ancient word. This reflects Duan Yu cut the word view.
