In Gurindji Kriol, all interrogative pronouns are derived from Kriol. These Kriol interrogative pronouns are not synchronically segmentable words, however many are derived from two English words, e.g. wijei ('where' < which way), wijan ('who' < which one). Others are single words such as weya 'where', wen 'when'.
One example of a synchronically segmentable compound expression can be found, wattaim. This is considered to be synchroncially segmentable because other taim expressions exists.
