 Hello! One of the most common complications of simple morphological analysis is that morphemes may have different shapes under different circumstances. This phenomenon is referred to as morphological alternation. The subfield within morphology is called allomorphy. In the virtual session, where you will find several e-lecture videos, we will define allomorphy first and we'll then look at different types of it. As an extra, we will also look at morphographic alternation in present-day English. Well, and as usual, 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 task with several questions about morphological alternation. Easy to answer after the virtual session. Well, and the practical provides you with data, as usual, data ready for analysis. Primarily English data but also data from other languages. You'll profit a lot from this unit, I'm absolutely sure.
