Especially in the first half of the twentieth century, language was viewed as a vehicle for the transmission of facts and ideas. Later on, scholars working in linguistic frameworks such as Functional and Cognitive Linguistics, (Historical) Sociolinguistics and Functional Sociolinguistics, have emphasized the social relevance of language, focusing, for example, on linguistic concepts such as deixis, modality, or honorific language, or embedding larger linguistic patterns in their social contexts, through notions such as register, sociolect, genre, etc. The main aim of this article is to systematize these observations, through an investigation of how the central, though ill-understood notion of “social meaning” can be captured. The starting point for the discussion is the work that has been done in the framework of Systemic Functional Linguistics. This framework distinguishes “social” (“interpersonal”) meaning from two other types of meaning, and offers a typology of different types of contexts with which these different meanings resonate. In order to achieve a more satisfactory account of social meaning, however, I argue that we need to connect to a theory of how signs convey meaning. The discussion is relevant for Ancient Greek in its entirety, but focuses specifically on Post-classical Greek: as a case study, I discuss five private letters from the so-called Theophanes archive
