本論文探討「很X」構式在口語語料中的語意變化，透過「很X」在口語語料庫及電視節目語料中的分布，分析「很X」語法化及詞彙化的情形，藉由語言學的角度，提供未來華語教學實用多樣的內涵。 過去相關文獻多集中於構式、詞類的分析，較少使用口語語料作為研究素材，而言談過程常是造成語言變化的重要因素，因此本文應用語法化及詞彙化理論，探討政治大學口語語料庫及公視節目「爸媽囧很大」中「很X」的分布情形，分析詞類結構、句法範疇及字數三個方面。兩個語料來源中「很X」的分布情形一致，「很」的語法化一直演變，「X」可擔任的範疇向其他詞類擴張，也可以由單詞、詞組、句子等字數不同的單位擔任。「很X」也藉由詞彙化持續演變，「很X」凝結為一個單位，用以修飾其他詞組或是句子。「很」除了保有表示高程度的副詞功能外，亦開始具有突顯「X」特性的功能，與特定詞類搭配時，「很X」必須一起出現才足以表達說話者的意思，這些現象顯示了「很X」的主觀性有逐漸提升的趨勢。本文以語法化和詞彙化理論來分析討論口語語料中「很X」的句法語意變化以及分布情形，研究結果可提供華語教學者進行相關學術研究、編撰教材以及實地教學的素材來源。 / The study aims to investigate the syntactic and semantic changes of hěn X constructions in spoken copora. Many studies have discussed the history of hěn, the development of its degree adverb function and the host expansion of X. To understand the gradual changes of hěn X in daily usages, the study, extracting the data from the NCCU Corpus of Spoken Chinese and Taiwan Public Telivision show, examines the grammaticalization and lexicalization patterns of hěn X . Several findings are found. First, the syntactic and semantic distributions of both sources are consistent. While adjectives and stative verbs still claim the majority of X, new categories of words are discovered, showing host expansion of hěn X. Second, not only words but also phrases and clauses can play the role of X. The flexibility of the length of hěn X demonstrates the gradual grammaticalization of hěn.On the other hand, hěn X can also be used as a unit to modify other grammatical constittuents, showing lexicalization process is also happening regarding. In particular, when hěn X is regarded as a unit, hěn appears to be obligatory, not only indicating degree but also highlighting the characteristics of X. The analysis of the spoken materials also clearly demonstrates that subjectivity is increasing in hěn X. These findings of hěn X in spoken copora can be applied to linguistic studies and Mandarin teaching.
