In this book, I demonstrate how people in conversation (and other forms of communicative practices) on-line construct working, and re-usable, systems of linguistic resources, through turn-taking and a method of turn construction (recycling with différance), which together structure material at hand - syllables and intonation units - like a language.

Moreover, I explore a number of properties of such systems, in particular their character of embedded and dynamic systems, solidly entrenched in space, time, and social relations.
