Build 1 - Think of, look up, write down and practice saying other questions which begin with 'Nyayararr ...' eg 'What are you making?'
Build 2 - How would you say in Wamba Wamba 'What was I saying?' (Clue - use the same pronoun and verb but add the ending for 'I' to 'nyanya' and ending for the past tense (or already happened) to the verb 'kiya')
