Crosslinguistic Influence: Transfer to Nowhere?

The literature on crosslinguistic influence (Sharwood Smith and Kellerman 1986) or transfer , as it has been traditionally called, is by now quite extensive, as befits a topic which has been wreathed in controversy ever since the fledgling days of second language acquisition (SLA). Perhaps few other research interests have been so affected by shifts of paradigm or fashion; yet whether we consider its importance primary or peripheral, an understanding of the part played by knowledge of one's first or other languages in the acquisition of a second remains an essential goal of SLA theory.
