Poetry, as a common style of writing, has a significant place in human cultural system. Poetry has also attracted the attention of various researchers. However, while past works on poetry focus mainly on those aspects such as rhythmeric characteristics, meaning construction, rhetorical application and arts of language, grammatical violations in poetry have been largely neglected. This is unfavorable in view of understanding of language fact as well as exploration of core grammatical rules in a language system. Under the theory of “special linguistic zone”, this thesis has conducted an investigation of innovations in poetic language and attempted to explain relevant phenomena using current theory of modern linguistics. Given the scople of a single research project, my work is restricted to the study of four carefully selected categories of content words, namely verb, noun, adjective, and pronouns. I have examined various types of innovative usage such as syntactic positioning conversion, free usage of bound morpheme, semantic mismatch, overlap, redundancy and contraction. This thesis has made contribution in the following three areas: First, an overall investivation of poetic language has been conducted with the help of large-scale poetic language corpus. A comprehensive discussion has been done about the unconventional grammatical phenomena in poetic language and grammatical violations in the four types of content words. Second, it demonstrates the interactive relationship between poetic language and non-peotic core grammar rules. Grammar is an organic system, and there exists influence amongst grammars of different styles of writing. Through investigating violations of core grammar rules observed in poetic language, the interaction between poetic language and core grammar rules are demonstrated and the understanding of core grammar is deepened. Finally, it reveals the theoretical significance of grammatical violations in poetry. As a widely used style of writing, language features in poetry will have an important impact on ordinary language. As one type of “'special linguistic zone”, the innovative use of poetic language provides a valuable window for understanding language mechanism, explaining language variation, and predicting language development. Keywords: modern poetry; content word; grammatical violation; style of writing, special linguistic zone; defamiliarization.

詩歌作為一種常見的語體，在人類的文化體系中佔為重要的地位。詩歌語言也因此吸引了眾多學者的關注。但以往研究多集中於詩歌的韻律特徵、意義構建、辭格運用、語言藝術等，詩歌語法的突破未能引起學界應有的關注。這不利於認清語言事實，也不利於把握背後的核心語法規則與語言機制。 本文在“語言特區”的視域下，考察詩歌語法中的創新現象，並當试利用當代語言學前沿理論做出合理的解釋。為了討論的深入，我們将研究範圍封閉在動詞、名詞、形容詞、代詞等四類實詞，具體涉及它們句法位置的安排、詞類轉換、黏著語素自由使用、語義錯配、重疊、冗餘、縮略等各類創新用法。本文的主要貢獻有三點:首先從宏觀上勾勒出詩歌語言概貌。基於大規模詩歌語料庫提供的語法事實，以四類實詞為突破口，全面探討詩歌語言反常規語法現象，有助於從總體上認識詩歌語言的概貌。其次，揭示詩歌語言與核心語法規則的互動聯繁。語法是一個有機的系统，不同語體之間的語法會互相影響、渗透。通過探討詩歌語言對核心語法規則的突破及核心語法對其的管控制約，清晰地揭示詩歌語言與核心語法規則的互動聯繁,深化對核心語法的認識。最後，揭示詩歌語法突破所蘊合的理論意義。詩歌作為一種廣為流傳的文體其語言特徵必将對日常語言產生重要影響。作為“語言特區”之一的詩歌，其所發生的語言創新用法為深刻認識語言機制、解釋語言變異、預測語言發展提供了一個寶貴的視窗。
