Previous studies have shown that intentional learning through explicit instruction is effective for the acquisition of collocations in a second language (L2) (e.g. Peters, 2014Peters, , 2015, but relatively little is known about the effectiveness of incidental approaches for the acquisition of L2 collocations. The present study examined the incidental acquisition of collocational knowledge when learners encounter adjective-pseudoword collocations while reading. Forty-one L2 learners read a story containing six target collocations in a classroom setting. One week after the reading they were interviewed about their knowledge of the form, meaning and collocation of the target items (at recall and recognition levels). Participants were randomly assigned to one of two experimental groups, i.e. the 4-repetition group and the 8-repetition group. Results showed that collocational knowledge can be learnt incidentally from reading; that it is learnt at a similar rate to other lexical components such as form and meaning of individual words;and that the frequency manipulation in this study did not seem to have a significant effect on the acquisition of any of the aspects examined.

I IntroductionVocabulary is an essential component of language and it has a tendency to occur in multiword units (Schmitt, 2010), i.e. lexical units which consist of more than one word (McCarthy, 1990). However, despite the importance of mastering knowledge of different types of multi-word units for achieving high levels of language proficiency and fluency in a second language (L2) (e.g. Boers, Eyckmans, Kappel, Stengers, Demecheleer, 2006;Granger, 1998;Stengers, Boers, Housen, Eyckmans, 2011), research into the teaching and learning of multi-word units is still scarce.Vocabulary teaching traditionally tended to focus on individual words (Schmitt, 2010) and consequently, vocabulary learning studies also focused on examining the best approaches to teach and learn single words. However, vocabulary instruction research has recently started to examine the acquisition of lexical items beyond the single word, and collocation has been one of the types of multi-word units examined. Mackin (1978) already noted that learners of English could learn collocations from repeated exposures in reading or by explicit teaching in the classroom. Recent studies on the learning of collocations have indeed been conducted around these two main approaches: explicit/intentional learning and incidental learning. Intentional learning is the learning that occurs when there is a particular intention to learn a set of items (Nation, 2001), whereas incidental vocabulary learning is the learning that occurs when learners' attention is focused on understanding messages without a particular intention to learn a set of words (Ellis, 1999). The majority of empirical studies on the acquisition of collocations have examined intentional learning through explicit teaching/learning (e.g. Boers, Deme...
