ABSTRACT: Within systemic functional linguistics (SFL), the primary-tense Finite may be realized separately from the Predicator in affirmative declarative clauses through do, does, or did. Existing SFL research has related this marked choice to the textual foregrounding of the process, while other studies have associated affirmative do with polarity focus, contrast, correction, and confirmation. However, these descriptions do not by themselves explain how the process-foregrounding function of focal Finite do may be related to mode in the context of situation, or what analytical distinctions are required when rhetorical orientation, turn, medium, and channel are considered. This article therefore investigates the mode-related potential of focal Finite do by drawing on SFL accounts of finiteness, polarity, information structure, and mode. It offers a qualitative analysis of a systemic contrast, published corpus examples, and dialogue represented in a literary work. Where focal prominence is evidenced or independently warranted by contextual conditions, this marked pattern may foreground the occurrence of a process or the positive validity of a proposition. It finds that the marked do construction provides a distinct grammatical resource through which the occurrence of a process or the positive validity of a proposition may be foregrounded. In the examples examined, this foregrounding contributes, together with related clauses and contextual information, to a locally explanatory relation of meaning, the confirmation of a central claim, and the acknowledgement of an anticipated objection. Dialogue and monologue, spoken and written media, and phonic and graphic channels provide different conditions for identifying and interpreting these contributions. The study extends the process-foregrounding account of the Finite to its mode-related potential, while showing that an individual occurrence of do neither independently realizes nor determines a value of mode.
