Compound question words do exist; e.g. /ní ahoní/ 'by what?, why?'. Other single word question words are /-hamá/ 'which?' agreeing in noun class with the head noun, /mína/ 'which one? (from a given set)' (not agreeing to the head noun), /íne/ 'how many?' (not agreeing with the head noun) and /ahoní/ 'what?'. There is no question word 'how?'. The equivalents of questioning 'how?' are done with the question clitic /-mo/ 'what?, how?'
