The take-away message from this book is quite simple: studying connectives and discourse relations matters because they represent cornerstone elements of discourse coherence. Throughout the book, our aim has been to illustrate the wide variety of research produced over the past decades on these two central notions. We have seen that although both concepts are intrinsically related, they cannot be entirely merged. Discourse relations can be conveyed in the absence of connectives through simple juxtaposition, and connectives can in many cases be used to convey more than one discourse relation depending on context.
