We reply to Erlewine and Kotek’s (2018) claim that the phenomenon of covariation under focus ( Tanglewood sentences; Kratzer 1991 ) is subject to syntactic islands and that it should therefore be handled by a focus movement theory (contra Kratzer’s view). We present novel data that are at odds with Erlewine and Kotek’s conclusions and demonstrate the necessity of an island-insensitive mechanism to capture focus covariation. We revisit Erlewine and Kotek’s main arguments against such a system and show that they are systematically confounded. Moreover, removing the confounds cancels the force of the arguments, corroborating the central point of this article.
