“去”的基本语义特征是[+离心]，即“从所在地到其他地方”，表离心义的“去”义词存在普遍性的多功能现象。我们将四种语系的23种语言纳为样本，借助类型学的语义地图理论，以广义的语义标准为筛选条件，以跨语言“去”义词的丰富用法为研究对象，最终确立了18个节点：离心、位移、存现、状态变化、可能、程度、过去时间、目的、处所、与事、补语、将来时、持续体、实现体、话题、接续、情态和语气。在功能聚合、语义分析和认知解释的基础上，进一步构建了跨语言“去”义词的概念空间和语义地图，最终得出了其功能扩张路径、语义关联度和语义演变机制。

我们发现，“去”义词在人类语言中具有显赫性，但不同语言的显赫度不同，具体主要表现为：

一、共性上，“位移”和“离心”作为“去”义词概念空间的核心节点，从基本语义范畴到句法功能范畴再到语用交际范畴不断向外扩张；

二、个性上，汉语普通话及方言的显赫度较高，以南方方言为最，这可能来自于古汉语的继承；

三、历时上，“去”义词主要经历了12条功能扩张路径，但其演变路径不等同于共时蕴含关系；在语义演变中，隐喻、推理和主观化作为三大成因机制，其中隐喻主要发生在语义发展早期，而推理和主观化则贯穿全过程。此外，汉语普通话以及诸多南方方言已经发展到“概念功能＞语篇功能＞人际功能”的高级主观化阶段，其他语言则基本处于概念功能、“概念功能＞语篇功能”或“概念功能＞人际功能”的初级/中级阶段；

四、趋势上，将来时→情态、位移→离心、位移→目的这三条发展路径的语义关联度最高，最具有预测能力。

The basic semantic feature of "GO" is [+andative], and there is a universal multifunctional phenomenon of "GO" with centrifugal meaning. We take 23 languages of four language families as our sample, and adopts the Semantic Map as our theory. Besides, we use the broad semantic criteria as the filtering condition, and takes the rich usage of cross-linguistic of "GO" as the research object. Finally, we establish 18 nodes: centrifugal, displacement, existential, state change, possible, degree, past time, purpose, premises, place, dative, complement, the future tense, durative aspect, realized aspect, topic, continuity, mood, and tone. Based on the functional distribution, semantic analysis and cognitive interpretation, we further construct the conceptual space and semantic map about cross-linguistic of "GO", and finally derive their functional expansion path, semantic relevance and semantic evolution mechanism.

We find that the meaning of "GO" have prominence in human languages, but the degree of prominence varies from language to language, mainly in the following ways.

Firstly, in terms of commonality, "displacement" and "centrifugal" are the core nodes of the conceptual space of "GO", which are constantly expanding from the basic semantic category to the syntactic functional category and then to the communicative category.

Secondly, in terms of personality, Mandarin Chinese and dialects have a higher degree of prominence, with southern dialects being the most prominent, which may come from the inheritance of ancient Chinese.

Thirdly, in the semantic evolution, "GO" have mainly undergone 12 functional expansion paths, but their evolutionary paths are not equivalent to co-temporal implication relations. Metaphor, inference and subjectivation are the three major causal mechanisms, among which metaphor occurs mainly in the early stage of semantic development, while inference and subjectivation occur throughout the whole process. In addition, Mandarin Chinese and southern dialects have already reached the advanced subjectivation stage of " ideational function > textual function > interpersonal function", while other languages are basically at the stage of conceptual function or "conceptual function > textual function" or "conceptual function > interpersonal function". So, the other languages are at the primary or intermediate stage.

Fourthly, in terms of the trend, the four developmental paths of "future tense→mood"，"displacement→centrifugal" and "displacement→purpose"have the highest semantic relevance and the most predictive power.
