The “Natural Order” of Morpheme Acquisition: A Historical Survey and Discussion of Three Putative Determinants

Abstract

The paper discusses the history and implications of the so-called “morpheme” studies. A brief overview of L1 research in this regard is followed by a more detailed discussion of L2 research. Thereafter, the paper explores the impact of three putative determinants of acquisition order: semantic complexity, input frequency, and native language transfer. The possible role of these determinants in accounting for perceived differences in L1 and L2 acquisition orders is also discussed, along with their implications for various theoretical perspectives on language acquisition. The paper concludes with both practical applications and criticism of the existing natural (morpheme) order studies as well as suggestions for future work in this field, such as investigating target languages other than English and developing a multi-determinant approach to acquisition order.
