岳西县地处大别山东南部，为安庆市下辖县，境内多通行怀岳片赣语。岳西方言中有一类成分，如“些”“跟”“半”“边下/边上”“往里”等，可以置于时间名词后，起改变其语义赋值作用，并可以附带非强制的消极感情义，类似于普通话中的“许”“前后”“左右”，可称其为模糊时间标记。以核证过的方言例句材料为基础，对岳西方言中此类成分的语法和语义特征进行描写及分析归类，进而与普通话中的同类成分进行比较。从来源看，该类模糊时间标记都是由动词虚化、表示空间模糊或数量模糊抽象到时间模糊而来，并都不同程度地伴随着语法化现象。从类型学角度看，概数助词、空间模糊、动词虚化表示模糊时间的用法在人类语言中可能存在普遍性，还有进一步探讨的意义。

Yuexi county is located in the southeast of the Dabie Mountains, and it忆s under the jurisdiction of Anqing. The Huaiyue Gan Dialect is widely used in this county. In Yuexi Dialect, there is a category of words, such as xie （some）, gen（behind）, ban（half）, bianxia/bianshang（about）, and wangli（inward）. They can be placed behind temporal nouns, to change their semantic values and attach optional negative emotions, like xu（about）, qianhou（before or behind） and zuoyou（or so） in Mandarin Chinese, which are called marks of fuzzy time concept in this paper. Based on verified dialectal example sentences, grammatical and semantic features of such marks of fuzzy time concept in Yuexi Dialect were described, classified and then compared with similar vocabulary in Mandarin Chinese. From the perspective of origin, it can be seen that such marks of fuzzy time concept are all derived from functionalized verbs or abstraction from spatial fuzziness or from quantity approximation. Moreover, they are more or less grammaticalized. From a typological perspective, it may be universal in human language to denote fuzzy time with numerical approximations, spatial fuzziness and functionalized verbs, so the study can be furthered in the future.
