This "poster" (provided in the form of a handout and a 5-minute
lightning talk) offers a new compositional semantics for relative
pronouns, taking into account their morphological relation to
interrogative pronouns (syncretism or containment). I argue that
relative pronouns are derived from interrogative ones by adding a
R(elative)-particle, semantically a focus-sensitive particle (akin to
Rooth's squiggle or Hagstrom/Cable's Q-particle) which, together with a
relative complementizer, participates in establishing the semantic
relation between the nominal head and its relative-clause-internal
representation, as entertained in the matching analysis.
