This study investigates the linguistic patterns and social functions of laughter-talk within naturalistic discourse. Alan Partington, a scholar specializing in corpus linguistics and discourse analysis, utilizes large-scale data sets to examine how laughter is embedded in conversation. The book argues that laughter is not merely a reaction to humor but a complex communicative tool used to manage social interaction, mitigate conflict, and signal alignment between speakers.

Experts in the field of linguistics recognize this work as a significant contribution to the study of non-verbal communication and discourse analysis. Readers often highlight the technical rigor of the corpus-assisted approach, noting that it provides a concrete framework for analyzing phenomena that are typically considered difficult to quantify.
