助动词“得”的情态语义分析——兼论与“要”的情态义差别

Comparative Study of the Meaning of Chinese Auxiliary Verb “dei”and “yao”

助动词"得"(děi)可表义务情态和认识情态。义务情态又分可选择和不可选择两种。就表义务和认识情态上,"得"和"要"出现了重叠的情况。但由于情态来源的不同,两者在情态义的具体呈现上仍存在一定的差异。

The Chinese word ＂dei＂ can express priority and epistemic modality. The former includes the deontic modality. There are some similarities between dei and ＂yao＂ in terms of the deontic and epistemic modality. The two modal verbs, however, still have a distinctive difference due to the different sources of words.
