After the success of the first workshop on Polar Questions Across Languages (POQAL), we are launching a second one. This time, the focus will be on form. How are polar questions expressed in syntax, morphology, intonation? How do components of the grammar of each language constrain and determine these ways, e.g. in the inventory of functional categories, the expression of negation, focus, polarity, intonational characteristics? How do fine grammatical components correlate with fine components of meaning? What crosslinguistic generalizations can be made in this new level of granularity?
