Memorable repetition: The role of letter repetition in brand names and social media marketing

 In this article, the role of letter repetition as a paralinguistic feature is studied in social media in order to help companies select the most repeated letters in words for devising brand names and the most effective sentences in marketing and advertising. The role of letter repetition as a paralinguistic element in advertising with the focus of the effect of this factor on the audience has not been studied in the Persian language. For this purpose, in order to find the frequency of the repeated letters, Instagram and Telegram social media were selected for data mining and five most repeated letters recognized. For the validation of the data at this phase, a questionnaire was devised and distributed among the students at the universities in Tehran and their families. In this way, the hypotheses regarding the most repeated letters and their use in advertising were also tested. Moreover, the quality of the words with letter repetition as being pronounceable was also studied and the use of four letters in case of being beautifully pronounceable was verified for the use in advertising and brand names.
