1. Introduction

Explored how the 'there' construct expresses subjective meaning through referential changes in addition to expressing objective meaning. Traditional research regards the 'there' construct as an objective construct that expresses both existing and implicit meanings, analyzing the syntactic and semantic features of the sentence beginning 'there', predicate verb, and noun phrase, as well as how they collectively constitute the objective meaning of expressing 'something exists somewhere'. However, this study suggests that the 'there' construct can also express subjective meaning, due to the changes in referential elements of its prototype syntax.

2. Guiding words: the change from distant to close and the change in speaking perspective

Explored the change of the introductory word 'there' from far to near and its impact on the perspective of speech. The non existential meanings expressed by the 'there' construct are diverse, including presentation, introduction, and discourse, and the existential meaning is only one of them. When expressing non existence meaning, 'there' can be replaced by 'here', reflecting the speaker's perspective shift. When 'here' replaces' there ', although it retains a certain spatial meaning, the specific present meaning becomes abstract, indicating that the speaker's perspective is from far to near, containing a reminder meaning. For example, the difference between 'there is a mango' and 'here is a mango' lies in the physical and psychological distance between the speaker and the mango. In addition, the transition from there to here also reflects the adjustment of the speaker's perspective from non speaker centered to speaker centered, that is, from objective to subjective. Langacker's theory suggests that this shift in perspective is a subjective process. Finally, there and here not only represent physical distance, but also reflect psychological distance, such as the different usage of 'there is a man that I like very much' and 'here is a man that I like very much'. In summary, the referentiality of 'here' as a spatial indicator has weakened, but it has gained the function of discourse guidance, reflecting changes in the speaker's observation style and speaking attitude.

3. Mode of existence: increase in detail and referential changes and subjectivity in modernization

Explored two changes in the expression of existence: increased detail and modernization, and how they affect the referentiality and subjectivity of the 'there' construct. The increase in detail is achieved by replacing the state verb 'be' with a cognitive or postural verb, which adds specific information to the mode of existence, thereby increasing recognition and the speaker's attitude meaning, but overall it still maintains declarative nature. Modernization emphasizes the simultaneity of time by using dynamic verbs in the general present tense, which eliminates the referential nature of tense and instead expresses the speaker's attitude and perception. This usage enhances subjectivity and expressiveness, while weakening referentiality. Through these changes, the 'there' construction can better reflect the speaker's attention to the present and the guidance of the listener's attention, while also reflecting that tense only expresses modal meaning in certain situations, rather than temporal meaning.

4. Existence: Referability in a defined form and evaluative in a copied form

In the chapter of the paper "Existence: General referent in Definitive Form and Evaluative in Copy Form", the referential changes of noun phrases in the "there" construction and their impact on subjective meaning are explored. Noun phrases usually appear in indefinite form in the 'there' construction to express new information, but in practical use, noun phrases can break through this limitation and appear in definite or copied form. Formal noun phrases do not express high referentiality in the 'there' construction, but rather have weak referentiality, providing a semantic basis for expressing declarative (subjective) meanings.

5. Hidden existence: Weakening referentiality and increasing subjective interpretation possibilities

Explored the impact of the implicit presence of prepositional phrases in the 'there' construction on referential and subjective meanings. When prepositional phrases exist, they enhance the determinacy and referentiality of the object through spatiotemporal positioning, giving the construction a stronger objective meaning of existence. When prepositional phrases are omitted, the certainty and referentiality of the presence of the object decrease, but the possibility of subjective interpretation increases. For example, omitting the 'there' construction of the place of existence more expresses the subjective meaning that the speaker wants to convey, leaving more room for the listener's imagination. Therefore, the emergence and referential changes of prepositional phrases are directly related, affecting the subjectivity of discourse and the subjective meaning of construction.

6. Conclusion

The referential changes and subjective meaning generation of the There construction reveal the multifunctionality and polysemy of language; The conversion of reference into statement is a key mechanism for the generation of subjective meaning; The expansion of form and function is closely related to changes in meaning, demonstrating the dynamism of function and meaning; The research orientation of static knowledge systems cannot fully explain the actual language use; A dynamic and dialectical research orientation is more conducive to observation, description, and interpretation; A deep understanding of the dynamic regulatory role of language function and meaning can help to explain the resolution of syntactic limitations more reasonably and improve the level of theoretical construction.
