 Hello, I'm sure you already know that compounding, also referred to as composition, is a word formation process that involves at least two base forms or two lexemes. This unit introduces the basic techniques of classifying compounds semantically, as well as the options for defining compounds according to their combinatory possibilities. Start with a virtual session where we will first look at headedness issues, that is, we will specify the heads of compounds using syntactic criteria. With this in mind, we can look at the semantic contribution of the head and thus define different types of compounds. If you don't know where to start, use the question sheet with its video links and hyperlinks as default guidance. The mastery worksheet is a dynamic multiple-choice test with several questions about compounding, easy to solve after the virtual session. Well, and the practical exhibits compound data, ready for analysis and research. And here we confine ourselves to data from present-day English. I'm sure you will like this unit, since it contains a number of interesting research questions.
