The relevant interrogatives in Kriol speakers are hu 'who’, wotaim 'when, what time’, weya 'where' and wijei 'where’ (directional); the same form wijei also means 'how' but is used alternately with hau. The directional 'where' form is not considered here, but considering one variant of 'how' leaves us with two compound expressions. The second part in both of them can be considered productive: -taim in wotaim recurrently forms temporal adverbials such as reintaim 'in the wet season', moning-taim 'in the morning', dina-taim 'at lunchtime'. The suffix -wei in wijei forms other adverbials of manner, e.g. blekbala-wei 'Aboriginal way (of doing/saying things), seim-wei 'same manner/way'.
