1. Introduction

Explore the three language description paths of formal grammar, construction grammar, and partial grammar, analyze their historical origins, methodological features, and complex correspondences. Formal grammar centers around vocabulary and focuses on the behavior of vocabulary combination; Constructive grammar studies the pairing of form and meaning in language and mental representation; Local grammar focuses on specific discourse meanings or functions, using semantic role analysis in local contexts. The article first sorts out the development background, basic concepts, theoretical propositions, and methodological characteristics of the three, and then explores their convergence, differences, and limitations. It proposes to analyze grammatical forms from a local grammar perspective, forming a "meaning form combination" to describe the pairing of form and meaning or function in more detail, which helps to identify and recognize structures.

2. Overview of Formal Grammar, Constructive Grammar, and Partial Grammar

In depth exploration of the origin, development, core concepts, and interrelationships and differences among the three language description paths of formal grammar, structural grammar, and partial grammar. Formal grammar originated from British descriptive linguistics, emphasizing the inseparable relationship between vocabulary and grammar, as well as the close connection between form and meaning. Scholars such as Sinclair and Francis have revealed the criteria for determining forms and their application value in language teaching through corpus analysis. As a part of cognitive linguistics, construction grammar was proposed by Goldberg, focusing on the pairing, unpredictability, and frequency determination of form and meaning. Its research focuses on the characteristics and cognitive representations of construction. Local grammar focuses on the lexical and grammatical implementation forms of specific discourse meanings or functions, using local conceptual categories for structured description and emphasizing functional analysis.

3. Identification and recognition of structures under complex correspondence between "form structure"

This chapter delves into the complex correspondence between form and construction, proposes the "meaning form combination" method of local grammar, and applies it to construction recognition and identification. By analyzing the local grammar of ADJ at n and V n about n forms, the intricate correspondence between forms and constructions is demonstrated, and the "meaning form combination" is used to establish and describe constructions. Research has found that the semantic groups divided by formal grammar are based on the intuition of native speakers, while local grammar analysis provides a standard for dividing semantic groups. For example, the ADJ at n form can express two evaluation meanings: emotional attitude and ability evaluation, forming two semantic groups. Through the analysis of "meaning form combination", V n about n forms can identify six semantic groups and construct at least seven local grammatical forms.

4. Conclusion

We discussed the advantages, problems, and limitations of formal grammar, construction grammar, and local grammar, and proposed the "meaning form combination" analysis method, aiming to establish the connection between the three, narrow the differences, and improve the rigor and accuracy of analysis. This method not only helps to identify constructs more systematically, but also can explore the application value of the three in language description and teaching. At the same time, the chapter also points out that formal grammar and partial grammar focus on the social functions of language, while structural grammar explores the mental processes and cognitive mechanisms of language. The integration of the three at a higher level requires philosophical considerations.
