Translation:Flowers smell good
start with the verb "kunuka = to stink", then apply applicative transformation a -> ia to get "kunukia = to smell good".
then because maua is a ji-ma class noun and it is plural and it's the one doing the verb, add the "ya" prefix plus the "na" present tense affix to get "yananukia" = "that plural ji-ma class noun smells good".

i am still trying to understand the generic rules for what the applicative transformation will do to verbs.
