This entry offers a summary of the origins of emoji and recent scholarship on their meaning and use as part of electronically mediated communication. Emoji are, at their most basic, pictograms used in communications via texts, chat apps, and social media platforms, and are part of a broader group that some scholars have termed “graphicons,” a set of graphemes used in online communications that includes emoticons, stickers, and animated gifs. Since their first appearance in the late 1990s, emoji have rapidly expanded to include an array of representations of feelings, people, objects; however scholarly debate continues as to their function in online interaction, and the degree to which they effectively serve a disambiguation function in communication.
