I sometimes do the same thing for my classes.  The midterm I just
finished giving my students had the following morphology data on
it.  Task:  Separate out all the morphemes, and give a simple rule
to explain any cases where a morpheme has more than one form.
(This problem should prove much easier than Kristian's...)

(Note: "e" = schwa, "n" = [N] before a velar)

        midun           "I walk"
        bindat          "he sleeps"
        midunge         "they walk"
        namingey                "you (pl) sang"
        nelalangim              "we worked"
        nukbiy          "you (sg) ate"

        ukbit           "he eats"
        amin            "I sing"

        nelalange               "they worked"
        miduy           "you (sg) walk"
        lalay           "you (sg) work"
        bindangey               "you (pl) sleep"
        nelalat         "he worked"

How would you say "you (pl) ate"?
