Previous experimental work on the processing of clausal ellipsis with contrastive remnants shows a Locality preference – DP remnants are preferentially paired with the most recently encountered DP correlate in the antecedent clause, even in the presence of contrastive prosody or semantic bias favouring a non-local correlate. The Locality effect has been argued to arise from the language processor consulting (default) information-structural representations when pairing remnants and correlates, yet direct evidence for the information structure hypothesis for Locality has been difficult to obtain. Estonian is a flexible word order language that optionally marks Contrastive Topics (CTs) syntactically, while allowing for the linear distance between a CT subject correlate and remnant to be held constant, in order to rule out a Recency explanation for the Locality effect. In an eye-tracking during reading experiment with case-disambiguated subject and object remnants in Estonian, we see asymmetries in the Locality preference (i.e. object advantage) following canonical Verb-second antecedent clauses and subject CT-marking Verb-third clauses. This provides novel evidence for fine-grained information-structural representations guiding the processing of contrastive ellipsis.
