In this book an introduction to the grammatical view of the scalar implicature phenomenon is presented. A detailed overview is offered concerning the embeddability of the exhaustivity operator, and the contextual dependance of the alternatives generation process. The theoretical implications of the grammatical view with respect to the abductive character of the scalar implicature are also discussed. A pragmatic account of the assertive content is proposed in correlation with a blindness-based account of the semantic content carried by scalar sentences, in order to ensure that the information globally conveyed by the latter is sometimes different from the semantic content automatically generated. -/- .
