 Welcome. This unit investigates two further functions that are associated with the elements of the verb group, mood and modality. In the virtual session, we will see that mood can be considered as a rudimentary inflectional category in PDE, but modality is realized syntactically by means of modal verbs and alternatives such as verbs, adjectives, adverbs and nouns. To be guided through the virtual session, use the question sheet with its hyperlinks, if you wish. The mastery worksheet is a dynamic multiple-choice test that provides you with the questions about mood and modality, certainly manageable after the virtual session. And in the practical, we have data for you. Data about mood and modality ready for analysis. Make use of all these options to achieve a deeper understanding of these two functional categories of PDE.
