 Semantics, and I'm sure you know that, is concerned with the study of meaning. This unit discusses the approaches to the study of meaning concentrated on word meaning, including a discussion of the most important theories. Furthermore, some selective problems of defining word meaning, such as ambiguity and vagueness, are presented. In the virtual session, which contains several e-lectures and micro-teaching videos, we will look at word meaning, draw a distinction between sense and reference, including some selected theories of word meaning. And we will end up with some problems such as ambiguity and vagueness. If you don't know where to start, use the question sheet, and its hyperlinks or its video links. The mastery worksheet is another dynamic multiple choice task, not problematic at all after going through the virtual session. And the practical, well the practical is all about meaning, the meaning of words, the meaning of sentences, thus another practical full of data ready for analysis.
