This paper examines the quantitative features of"够"in its use and evolution.The word"gou"can be combined with nouns,verbs and adjectives to form constructional groups.With the increment of subjec-tivity,"gou"is deflated from the objective sufficient quantity to the abstract degree quantity while it evolves from a verb of judgment to an adverb of degree.The fictionalization of semantic magnitudes led to the evolution of the verb"gou"into a degree adverb.The grammaticalization level is non-homogeneous,when it modifies ad-jectives the degree is the highest.The function of"gou"has been transformed from objective quantitative as-sessment to subjective fuzzy qualitative assessment.
