Abstract: No general consensus has been arrived in finiteness of verbs in Chinese since late 1890s. A sketchy review of the morphological changes during the development of Chinese shows that it is improper to treat the finiteness of verbs majorly on the basis of inflections. With the insights from Whorf’s cryptotype and Halliday’s cline, we can differentiate six types between typical non-finite clause and typical finite clause according to three parameters as follows: the appearance of subject, the verb as the main predicate, and the verb agrees with persons and numbers. It is found in the present research that the so-called pregnant clauses, the serial verb construction and the jianyu construction (similar to SVOC construction in English) can all be expounded within the types we proposed in a consistent way. In general, pseudo-non-finite clauses are prevalent in modern Chinese.
