In the recent past, an increase in globalisation has made the world a small place, so that intercultural encounters have become the norm rather than exception. Multilingualism and multiculturalism are widespread phenomena that shape today's world to a great extent. Every culture and language has its own set of norms and conventions for interacting and communicating with each other, whereby politeness plays an important role. This thesis is interested in the question whether multilinguals use and perceive (im)politeness differently depending on the language they use.
