Being literate likely has consequences for learning a second language, but surprisingly little research has been devoted to how emergent literacy affects second-language acquisition processes. Using a word learning experiment, we aimed to tease apart two possible ways through which literacy could impact second-language acquisition: through literacy-induced restructuring and through using written input in addition to spoken input. Totally, 166 (L1 Arabic and L2 Dutch) participants of varying literacy levels (emergent readers and more experienced readers) had to acquire eight words as names of people and pet animals, of which some only varied in one phoneme. Half of the participants received only auditory input to learn these names, and the other half also received written input. Bayesian mixed-effects models indicate that experienced readers are better able to acquire words and a phonological contrast than emergent readers, pointing toward a benefit from literacy-induced restructured linguistic representations. We also obtained anecdotal evidence that, although experienced readers seemingly benefit more from written input than emergent readers, the latter group could still use written input to a small extent. Possibly, written input might be beneficial, even though it cannot be properly decoded yet—at the very least it does not harm providing such input.
