In this chapter, I assess the classification enhanced and proposed in Chap. 3 by means of an empirical study that brings to light the evidence of conceptual discrepancies between languages. The empirical study involves language tests performed with native speakers of Chinese, Italian and Slovenian, who were asked to assess their perception of the degree of completion of the action expressed by verbs. The study attempted to prove two main ideas. (1) That unrelated languages show a greater degree of semantic discrepancy, which is due to structural differences between languages, but also to the idiosyncrasy of conceptualisation in the context of the native language. (2) That the interpretive freedom of the completion of Chinese monomorphemic verbs leads native Chinese speakers to focus more on the category of process than on result, linguistically, but also more generally. The main part of this chapter is devoted to the contrastive analysis and the interpretation of the results for the three languages studied. In the last part, I go into more detail on the use of aspectual markers collected in the language tests to show the different degree of interrelation between lexical and grammatical aspects in the languages studied.KeywordsLanguage testsDegree of completionConceptualisation of aspect
