The relative markers who, what, and that are not distributed according to case in Bahamian Creole but according to the human/non-human distinction. Thus, who is used for human referents, in both subject and object (cf. Example 225) function, whereas what and that are used primarily for non-human referents, also in subject and object function. However, what can also be employed for human referents (cf. Example 227).
