Among the many puzzles that language presents to the developmental psychologist, perhaps the most fascinating is the relative ease with which a toddler picks up a first language. Although infants know nothing of the rules of grammar and have only a fragmentary understanding of the physical and social world, they are able to master the core structures of language by the age of three. The ease with which children master their first language contrasts with the more painful and incomplete process of learning a second language in adulthood.
