Early Second Language (EL2) learners generally perform more poorly than monolinguals in specific language domains, presenting similarities with children affected by Specific Language Impairment (SLI). As a consequence, it can be difficult to correctly diagnose this disorder in EL2 children. The current study investigated the performance of 120 EL2 and 40 age-matched monolingual children in object clitic production and non-word repetition, which are two sensitive clinical markers of SLI in Italian. Results show that EL2 children underperform in comparison to monolinguals in the clitic task. However, in contrast to what is reported on Italian-speaking children with SLI, EL2 children tend not to omit clitics but instead produce the incorrect form, committing agreement errors. No differences are found between EL2 and monolingual children on non-word repetition. These results suggest that, at least in Italian, EL2 children only superficially resemble children with SLI and, on closer inspection, present a qualitatively and quantitatively different linguistic profile.
