The present study investigates the possibilities for adult learners to attain nativelikeness in the domain of lexis. Aspects investigated are general lexical knowledge (C-test), receptive deep knowledge, productive collocation knowledge, and productive lexico-pragmatic knowledge in a group of long-residency Swedish French second language (L2) users in France and a matched native control group. The analysis includes correlations between these different vocabulary aspects as well as their relation to the length of residence in the target-language (TL) community. The study reveals that it is possible for L2 learners to attain nativelikeness in general lexical knowledge and lexico-pragmatic knowledge, whereas deep knowledge and collocations are especially difficult for L2 learners, supporting earlier research findings. Furthermore, a strong correlation is found between general lexical knowledge and collocations, but surprisingly not between any of the other aspects, or between vocabulary aspects and length of residence. The results are discussed in light of individual differences in research.
