ABSTRACT
Recently, a number of methods for the analysis of discourse particles have been proposed within formal pragmatics. Taking the status of information in the common ground and information management by the speaker into account, in this research we propose an approach which incorporates the mechanism of Question Under Discussion (henceforth QUD). We connect QUD-based approaches with other non-officially QUD-based particle analyses and exemplify its application with new analyses of the particles in Central Thai. The relation between particles and intonation will also be briefly discussed through the analysis of the particle ná. We hope the fresh analysis will shed light on the information-related operation of discourse particles in general.
