Dear Frans and colleagues, The Chukchee-Koryak group have ordinal interogatives. You can find Chukchee details in the grammar by Skorik, summarized on my Chukchee webpage at http://privatewww.essex.ac.uk/~spena/Chukchee/chapter3.html#ord I also cite one or two examples of this in my paper on incorporation in Chukchee, Language 1995.
