The polarity-neutral existential copula jɛn(da) and the inherently negative existential copula furi(da) take their Theme argument as subject. An alternative is to use habu (or reduced ha) 'have' with existential meaning, either with a null subject, or with the 3SG pronoun as subject. This is clearly less frequent, and possibly represents Creolese influence.
