"Vague language refers to expressions with unspecified meaning (for instance, 'I kind of want that job'), and is an important but often overlooked part of linguistic communication. This book is a comparative study of vague language based on naturally occurring data of a rare combination: L1 (American) and L2 (Chinese and Persian) speakers in academic settings. The findings indicate that L2 learners have diverse and culturally specific needs for vague language, and generally use vague words in a more concentrated fashion compared with L1s. The book explores the interconnection and continuum between the linguistic realizations of a vague term and the functions it serves, and how 'elasticity' underpins the frequency and functions of vague language. The implication is that vague language may be integrated into the curriculum of English language teaching as part of L2 speakers' communicative competence. This book will be of great interest to researchers in the fields of intercultural education and applied linguistics"--
