In this paper a reflection is made about the pervasive phenomenon of linguistic errors, their possible nature and the role they seem to play in the processes of second language acquisition (SLA) in particular. An analogy is drawn between the concept of an 'interlanguage', as originally proposed by Selinker (1972;1996), and connectionist models of language acquisition and processing. Language processing, it is suggested here, seems to be governed mainly by a probabilistic system.
