Left peripheral topics and foci often differ with respect to resumption: in languages such as Italian, Tzotzil Maya, and Warlpiri, while fronted topics may be co-indexed with a pronominal form in the corresponding argument position, fronted foci correspond to a gap. However, this contrast does not universally apply. In languages such as Anyi and Baule, two Kwa languages of Côte d'Ivoire, subjects and animate objects must be resumed by a pronoun whenever they appear in the left periphery – independent of information structure. The question is whether this instance of cross-linguistic variation arises through differences in the syntax of left peripheral positions in various languages or in the conditions of resumption. The present study examines data from Kwa languages and concludes that the difference lies in the conditions of resumption, which are orthogonal to the syntactic differences between topics and foci. Resumptives have a dual nature in these languages, serving as anaphoric constants (true resumptives) in topicalization and as bound variables (apparent resumptives) in focus constructions. A survey of the relevant facts in further Kwa languages reveals that resumption is determined by factors that are independent from information structure and relate to the recoverability of empty argument positions.
