Chapter 1 provides an introduction and overview of the topics covered in the book. General extenders, adjunctive and disjunctive, are defined, exemplified and their internal structure analyzed. Four functions are described, with examples, as referential, interpersonal, personal and textual. Thehistorical development of some common forms is described, as well as the processes of grammaticalization. Certain forms are recognized as linguistic variables that align with social variables to represent social markers in different communities. Translation equivalents are identified in a range of different languages and in the speech of second language learners and those using English as a lingua franca. Ideas are presented for teaching general extenders as examples of pragmatic markers. Their multifunctionality is illustrated, together with some observations on their position within utterances, leading to a novel claim that some forms can be used as associative plural markers, a feature hitherto undocumented in English.

Chapter 3 focuses on the uses of general extenders that are addressee-oriented and express an interpersonal function in interaction. The underlying concept is described as intersubjectivity, which is tied to an awareness of the addressee’s needs. Participants in an interaction are taken to be cooperative fellow speakers, adhering toGrice's Quality and Quantity maxims. The use of adjunctive forms to indicate common ground can also create a sense of solidarity, indicating similarity, and hence also signaling positive politeness. In other situations, speakers can use disjunctive forms to signal negative politeness, that is, a concern with potentially imposing on the addressee. When general extenders are used as part of these politeness strategies, they are often described as hedges, used to indicate possible inaccuracy or imposition and a desire to avoid such things, resulting in an association with approximation.
