 Hello. This unit introduces the central aspects of defining the meaning relationship between words and objects. That this relationship, which is referred to as referential relationship or reference, is only indirect, has been known for a long time. For this reason, concepts in the mind are used as mediators between words and extra linguistic items. Hence, in the virtual session which contains one central e-lecture and several microlectures, we will look at reference, we will discuss types of reference, we will deal with approaches towards relating objects and linguistic entities, and we will work with concepts in the mind. Use the question sheet with its hyperlinks and its video links for guidance if you don't know where to start. The mastery worksheet is a dynamic multiple choice task about reference where the choices are presented successively, certainly manageable after going through the virtual session. And the practical provides you with data, that is, with words and sentences where you can test your intuitions and deepen your knowledge about reference.
