Most theoretical and empirical studies of discourse marker multifunctionality do not approach it using a formal, systematic annotation model. Drawing on a domain-function taxonomy, this study examines 270 tokens of the discourse marker ni zhidao in Chinese media interviews. All values of the two-dimensional model designed for the whole category of discourse markers apply to ni zhidao, demonstrating its equally potent affordance on a particular discourse marker case cross-linguistically. By putting this model to the test, we found that “emphasis” needs to be added to the original 15 functions in the model, and that domains and functions need to be treated as dependent layers of pragmatic meaning. Functions determine domains, and domains need to be regarded as macro-functions to which specific functions are attributed. As such, we tentatively put forth an updated version that provides finer granularity and greater affordance, shedding new light on the pragmatic meaning of ni zhidao and the speaker’s underlying communicative intent. We propose that the sample be divided into uni-functional and multi-functional categories before being analyzed within the updated model to capture the multifunctional discourse markers in the same context-specific utterances. This study has implications for the need of more exhaustive, speech-friendly annotation models of DM multifunctionality and the cross-linguistic adaptation or refinement of established DM annotation models to cater to the unique traits of spoken DMs in different languages.
