Epistemic Modality in Selected Presidential Inaugurals in Ghana

Abstract
This paper employed the qualitative research approach to investigate the use of epistemic modality (EM) in four selected inaugural speeches of ex-presidents in the fourth republic of Ghana. It was underpinned by the interpersonal metafunction in Hallidayan’s (1994) Systemic Functional Linguistics (SFL) theory which dovetails into the concept of EM. The analysis was done with the aid of corpus-based computer software—AntConc. The findings revealed a preponderant use of modal verbs with a frequency of 165 representing 84.2% while lexical verbs occur 13 times representing 6.6%. Adjectives and adverbs are minimally used with a frequency of 11 and 7 representing 5.6% and 3.6% respectively. The findings also revealed that Ghanaian presidents in the fourth republic dominantly use high values of EM to present themselves as bold, confident, committed and forthright in their utterances. Additionally, they were also communicatively sensitive as they use tentative markers when addressing sensitive issues. The study bears implications for pedagogy, theory and practice as it boosts the concept of EM and its appropriate use in political discourse.
