Language is fluid, and evolves over time. As emojis have become ingrained in communication, so have many other byproducts of the digital revolution, such as 'text speak' and predictive text. Each of these has contributed to reducing standards of literacy. However, if the primary goal of language is to communicate, many studies show that emojis actually bring clarity to otherwise ambiguous messages.
For example, a 2017 study by psychologist Linda Kaye found that participants were more likely to understand the nuance of ambiguous messaging when emojis were included. Kaye concludes, 'these symbols are not purely emotional, but they add layers of complexity and clarity to communication.'
