I'm still not clear on it.
1) Is ku a pluralising prefix? Or partial reduplication?
2) Does this morphology rule out all syllable-boundary consonant clusters except "nC"; for example, tosma and katsoi couldn't occur?
3) If we wanted to adapt a word like "elephant", it couldn't be elefant or elefante, could it? It would have too many moras. To say nothing of a word like "molybdenum" or "protactinium". Or am I misunderstanding?
