The basic grammatological unit in 
Vietnam’s Nom script and its relationship with those in Chinese script

Abstract

The basic grammatological unit (grapheme) is a universal one for all writing systems. Chữ 𡨸 is such a basic unit in Nom script. When analyzing chữ 𡨸, the basic unit of a derivative script such as Nom script, the researcher thinks that apart from attention paid to the relations to language units recorded by it, as basic units of the source writing system such as wen (文) and zi (字) in Chinese script, it is necessary for the researcher to attach importance to the corresponding relations right in this derivative writing system. The expression of chữ 𡨸 in the corresponding internal relations also needs to be taken into consideration as a documentary fact for the study of graphemes in writing systems renovated from the hieroglyphs of Chinese script in particular, as well as in grammatology in general.
