One of the linguistic consequences of globalization is the increase in the number of people communicating with each other in a language that is not their own. Studies have started to examine how non-nativeness affects people in their production and evaluation of discourse. This special interest section brings together a collection of empirical papers in a particular domain of non-nativeness in communication, that is, the use and effects of foreign languages in job and product advertisements. These papers investigate how the use of foreign languages is appreciated by non-native users, what determines the occurrence of foreign languages, how recall of foreign languages compares to the recall of L1 advertising, and whether foreign languages attract the readers’ curiosity. Together, these papers demonstrate the growing academic interest in non-nativeness in communication.
