 Hello. What are the main linguistics parameters to classify the world's languages and how are they realized? These questions constitute the central goals of this introductory unit to language typology. As usual we start with the virtual session and optionally use the question sheet as a default guidance to understand the central typological parameters phonology, structural typology and word order. This unit's Masui worksheets involves 20 questions on two levels with 10 questions each. Perhaps the most challenging part of this unit is its practical sheet, where you have to add examples of the main typological parameters of PDE and also if you wish of your mother tongue. A quite enjoyable task we hope. So we are sure you will enjoy this unit and good luck.
