Lila Gleitman and Cynthia Fisher explore the interaction of meaning and grammar in language acquisition. Based on three lectures given by Dr. Gleitman in the prestigious Blackwell-Maryland Lectures in Language and Cognition, the text has been substantially revised and re-worked to make it useful in undergraduate and graduate courses. The book provides this seasoned child language researcher with a platform to share her knowledge and expertise among students and scholars studying language acquisition and psycholinguistics.
