This introduction comprises four main sections. Section 1 introduces the overall theoretical architecture of Systemic Functional Linguistics (hereafter SFL) by way of contextualising the focus on interpersonal grammar in this special issue. Section 2 looks in more detail at the interpersonal discourse semantics underlying this work, briefly introducing the systems of negotiation and appraisal realised through interpersonal grammar. Section 3 turns to the concept of grammatical metaphor, a concept which bears critically on the realisation relationship between interpersonal discourse semantics and lexicogrammar in SFL. Section 4 comments on the challenge of intradisciplinary dialogue.

人际意义

本介绍包括四个主要部分。第 1 节通过将本期特刊中人际语法的重点置于语境中，介绍了系统功能语言学（以下简称 SFL）的整体理论架构。第 2 节更详细地考察了这项工作背后的人际话语语义，简要介绍了通过人际语法实现的谈判和评价系统。第3节转向语法隐喻的概念，该概念对SFL中人际语篇语义与词汇语法的实现关系具有重要意义。第 4 节评论了学科内对话的挑战。
