The last two decades have witnessed a growing interest in vocabulary items consisting of more than a single word in the field of English language teaching (ELT) (Nation & Meara, 2002, p. 36; Schmitt, 2000, p. 96). Researchers in the area came to notice that language is produced by native speakers as 'chunks' rather than single words (Schmitt, 2000, p. 42; Read, 2000, p.20).
