Age is by far the most underdeveloped of the sociolinguistic variables in terms of research literature. To-date, research on age has been patchy and has generally focused on the early life-stages such as childhood and adolescence, ignoring, for the most part, healthy adulthood as a stage worthy of scrutiny. This book examines the discourse of adulthood and accounts for sociolinguistic variation, with regards to age and gender, through the exploration of a 90,000 word age-and gender-differentiated spoken corpus of Irish English. The book explores both the distribution and use of a number of high frequency pragmatic features of spoken discourse that appear as key items in the corpus. Part 1 of the book provides an introduction, a theoretical overview of age as a sociolinguistic variable and a description on how to compile a small spoken corpus for sociolinguistic research. Part 2 consists of five chapters which investigate and explore key features such as hedges, vague category markers, intensifiers, boosters and high-frequent items of taboo language in relation to the variables, age and gender.
