This study problematizes the second language (L2) / third language (L3) initial state, questioning who the real initial state-learners are and whether it is the initial state that has been explored in some previous L3 studies that claim to do so. We will discuss the notion of initial stages in relation to the initial state. We argue that, depending on prior language knowledge, learners can – thanks to intercomprehension – advance rapidly from the initial state into the initial stages of interlanguage. We base these suggestions on data from a small-scale study in which 20 native speakers of Swedish assessed whether some Dutch, Finnish and Norwegian sentences were grammatical or not. The results from this study led us to a discussion of whether the leap from the initial state to the initial stages can be overcome more quickly, due to the clues from typological similarity on the lexical level that the learners are given.
