This paper proposes a novel syntax and semantics for apparent association of additive focus particles with the PRO subject of clauses embedded under control verbs (Heim 1992), combining the Movement Theory of Control (Hornstein 1999) and the Operator-Particle theory of focus syntax (Lee 2004; Hirsch 2017; Branan & Erlewine 2020). On the analysis developed here, embedded additive readings are derived by an additive focus operator associating with a copy of the controller DP in the embedded clause. The analysis solves two puzzles for previous work on this topic: the necessary presence of focus marking on the controller of PRO with embedded additive presuppositions, and the availability of embedded additive presuppositions in languages such as Japanese and Persian, in which focus particles attach unambiguously to the controller DP in the matrix clause.
