Punjabi is the language of the Punjab - the land of five rivers - of northern India and Pakistan. Primarily written in three distinct scripts, a unique feature of the language is that, along with Lahanda and the Western Pahari dialects, it is the only modern Indo-European language spoken in South-East Asia which is tonal in nature. It is recognised as one of the several national languages of India and Pakistan, and approximately forty-five million people speak Punjabi as either a first or second language. This Descriptive Grammar accounts for the linguistic and sociolinguistic properties of Punjabi and Lahanda/Multani. It explores the standard language, giving a comprehensive account of syntax, morphology and phonology. With a descriptive, typological and cognitive examination of the language, this is a comprehensive and authoritative description of modern Punjabi . This volume will be invaluable to students and researchers of linguistic theory and practice.
