SUMMARY
The paper is an extra-linguistic critique of Austin’s speech act theory. In the context of the paper, extra-linguistic issues capture those factors that “legitimize” violations from the norms of English which are evident in Austin’s theory. We investigate the strengths and weaknesses of the theory from a socio-pragmatic perspective, exploring discursively, the Nigerian existential experience. The critique hinges on three evolved theoretical concepts (Geoimplicature, Emergent Context and Pragmadeviant) in the investigation of the strengths and weaknesses of Austin’s speech act theory. The study finds out that despite the strengths of the theory, some postulations therein are bedeviled by the dynamics of human communication. Conclusively, the paper contends for an “illocutionary component” of meaning as opposed to the age-long “propositional component” of meaning.
