This paper focuses on some language resources for graduating
points of view in written Spanish language in the field of history. The analysis
is framed in systemic functional linguistic theory, a multifunctional theory of
language (Halliday with Matthiessen 2014), and focuses on the appraisal system, which organises
interpersonal meanings at the stratum of discourse semantics in language (Martin and White 2005; Martin 2019; White 2021). In particular, it considers the coupling
and necessary complementarity of graduation and engagement
subsystems, as part of the appraisal system, for building
intersubjectivity in texts. To achieve this purpose, the analysis explores the
role of the Spanish lexicogrammatical system of modality (modalisation
and modulation) in the construction of dialogicity in historical documents.
