This chapter demonstrates the explanatory power of an approach that grounds the analysis of natural-language meaning on the linguistic sign itself. Cases covered include the multifarious uses of the preposition for, verbal complementation with aspectual and causative verbs, the phenomena of control and raising in adjective + to-infinitive constructions, the use of wh- words with the bare and to-infinitives, the modal and non-modal uses of the verbs dare and need, and a meaning-based account of full-verb inversion and existential-there constructions.
