As a result, how a sender meant to send out a message versus how their addressee reads it sometimes differ. This can lead to uncooperative and confusing online communication. This paper set out to examine if (and what) effects different punctuation types have on the interpretation of meaning in WhatsApp communication, and whether one’s age or native language influences the perception of these markers. The punctuation types were the exclamation mark, ellipsis, periods, and no punctuation. Unlike previous studies conducted on this topic which focussed only on students, this study was conducted among 123 respondents from a wide variety of ages and countries. Through an online survey, participants were asked for their opinions and thoughts to different types of punctuation used in recurring but otherwise identical messages. Results indicated that different punctuation types elicit strong and differing views, based on what punctuation type is used, and that these types influence their feelings towards the message as well as to the personal state of their interlocutor. The most significant findings were found for ellipsis points and messages lacking any punctuation: ellipses can lead to very negative interpretations in respondents, and a lack of punctuation can lead to respondents feeling sidelined. Interpretations of certain punctuation types are influenced by a reader’s age and native language. Using Yus’ theory of a phatic internet and cyber literacy, this paper posits that the reason respondents assign these meanings to different types of punctuation is to avoid misunderstandings, form identities, and stay on good terms with people in a world in which most daily conversation happens online.Show less
