 More recently, the volumes Keenan and Paperno (2012) and Paperno and Keenan (2017) have a separate chapter answering a fixed set of questions about expressing quantification for each of 34 different languages (different also from those mentioned above), in order to make an extensive inventory of their expressive  resources.[37]  The approach is semantic: the questions are of the form “Can one express X in your language, and if so in what ways?”, which allows precise questions about conservativity, monotonicity, polarity items, monadic vs. polyadic quantification, etc. to be put to each language. The summary in the last chapter shows that many of the generalizations that hold for English, concerning the existence of expressions denoting certain quantifiers and the properties of those, hold in all or most of the other languages studied as well (Keenan and Paperno list 25 such generalizations).
