 Hello, this unit builds upon the unit on ambiguity, whereas the context of use usually selects one of the meanings of an ambiguous expression. In cases of vagueness, the context can add information that clarifies the meaning of the vague expression. In fact, there are various types of vagueness and they will all be discussed in this unit. Thus, the programme of the virtual session is clear. We will first look at the various types of vagueness and will then provide and put to test several criteria that distinguish vagueness from ambiguity. Use the question sheet for guidance. The hyperlinks and video links in it may help a lot. The mastery worksheet is a dynamic multiple choice test that shouldn't be problematic at all after going through the virtual session. Well, and the practical provides you with data as usual, data to identify types of vagueness and to differentiate between ambiguity and vagueness. So, good luck with this unit.
