In this paper, using the tenets of Situation-Bound Utterances and referring to Pragmatic Act Theory, the verb mordan, and its different realisations are analysed among Persian speakers. Through the analysis of authentic talk in interaction, this study aims to ponder nonstandard meanings of the term mordan and its different SBUs. The primary focus of the study is on strings of linguistic events as well as the “conventions of usage” or cultural understanding that may lead to standard and nonstandard meanings considering (...) mordan and its different SBUs. The findings suggest that the SBUs regarding mordan, a neglected sociolinguistic context, not only is affected by its actual situational characteristics but also by prior context encoded in utterances used, which manifests culture-specific ways of thinking. Overall, 19 SBUs and 7 generic categories were identified with regard to the verb mordan in Persian. This paper exhibits that mordan is a versatile verb, which, when combined with situational/contextual factors, conveys different nonstandard functions that fulfil social needs. This study will also refer to linguistic features underlying SBUs that are influential in assigning various distinct meanings to the verb mordan in Persian. (shrink)
