Nation-building is investigated in this study, via a linguistic instrument: the Pragma-crafting Theory. I contend that the Theory explainshow languagedirects education, peace, security, politics and other societal phenomena to evolve meaningful and sustainable development in Nigeria. Thus, the linguist is portrayed as a reformer of society. Recently published inAmerican Research Journal of English and Literature, the Pragma-crafting Theory is evidently one of the latest, emergent, linguistic theories for the analysis of discourse. It depicts language use, comprehension and function as conscious, systematic and people-driven phenomena. Insights from research in pragmatics, sociolinguistics, discourse analysis and semiotics inform the Theory. EVENT and TEXT are basic notions which anchor a wide range of concepts in the Pragma-crafting Theory. EVENT consists of interactive and non-interactive participants while TEXT consists of setting, theme and p-crafting features. Therefore, the Theory is particularly an extension of Mey. The findings of this paper are thought-provoking: communication acts (speech acts)and communication features such as indexicals (INDXL), shared macro-knowledge (SMK), shared contextual knowledge (SCK), shared knowledge of emergent context (SKEC), contextual presupposition (CP), geoimplicature (GI),behaviouralimplicature (BI), pragmadeviant (PD), object referred (OR), operative language (OL) and other discourse components are used by encoders (ENCs) of verbal elements (VEs) and non-verbal elements (NVEs) as critical instruments in effective policy-making, national mobilization, national cohesion and national progress.
