There is one interrogative element which is situated at the end of the sentence, namely the locative bô/ô:
Kikiê e ô?
[fish DEM where.is]
'Where is the fish?' (Maurer 1995: 139)
This locative interrogative is of Edo origin and exists in all the Gulf of Guinea creoles (bô in Santome and Fa d'Ambô, and ba in Principense). In my view, it is a verb, but Tjerk Hagemeijer analyzes it as an interrogative pronoun.
