Because of the pervasiveness of the text messaging medium, further understanding of meaningmaking practices in text messages is desirable. This study offers new knowledge of the potential uses and meanings of the full-stop in text messages. Although the full-stop has become infamous for its potential negative connotations in text messages, few studies have evaluated uses of the full-stop in varied emotional contexts. For this study, text message Discourse Completion Tasks (DCTs) detailing different emotional contexts were given to undergraduate students. The uses of full-stops in the text message responses elicited with the DCTs were evaluated via two methods of analysis. First, a basic content analysis was conducted for the purpose of understanding the relative uses of the full-stop in the differing emotional contexts. Second, a semiotic analysis was conducted to understand more fully how exactly the elicited fullstops were deployed and what meanings they might convey. It was concluded that the full-stop is not always a device with a negative connotation, and that, in certain circumstances, the fullstop may be seen as more appropriate than other punctuation marks. It may even be seen as a conveyer of formality, seriousness, or earnestness. The study offers practical knowledge of how a certain typographical device is used, as well as the more theoretical knowledge that punctuation devices, like words, can possess a certain semiotic elasticity: their uses and meanings can vary, depending on the contexts in which they are deployed and the people who write and read them.
