This book explores the syntactic and semantic properties of movement and adjunction in natural language. A precise formulation of minimalist syntax is proposed, guided by an independently motivated hypothesis about the composition of neo-Davidsonian logical forms, in which there is no atomic movement operation and no atomic adjunction operation. The terms 'movement' and 'adjunction' serve only as convenient labels for certain combinations of other, primitive operations, and as a result the system derives non-trivial predictions about how movement and adjunction should interact; in particular,
