Research on L2 pragmatic development forms the mainstay of many interlanguage pragmatic (ILP) inquiries. Yet promoting L2 pragmatic competence becomes an exceedingly demanding task when different constraints are brought to bear. This dilemma is due in large part to contrasting theories on interlanguage pragmatics development. From exposure to instruction, ILP research has long wrestled with the practical problems in the way of such development. Adding these together, the field is in dire need of practically meaningful research to address the full spectrum of both the pragmatic construct and the factors to foster its development. Intent on piecing together disparate sources of theory and data, this review synthesizes research regarding key considerations in L2 pragmatic development from cognitive, sociocultural, psycholinguistic and independent vantage points. Meanwhile, it summarizes the current knowledge on ILP development and draws out critical questions in connection with the past research. It is argued that there is a dearth of an integrative model for the acquisition of pragmatic competence, which renders several controversies surrounding L2 pragmatic development, especially that of the relationship between grammar and pragmatic development patterns, implausible. To serve that purpose then, a model for the acquisition of L2 pragmatic competence is expounded. In conclusion, a research agenda involving two prime research questions is outlined for future directions.
