“…In addition, formulaic expressions, collocations and idioms are mentioned among the topics that still pose challenges to CALL research (Levy, Hubbard, Stockwell, & Colpaert, 2015). Collocations like to commit suicide or heavy drinker are known to be difficult for L2 learners and have been addressed in various CALL studies (Chan & Liou, 2005;Daskalovska, 2015;Futagi, Deane, Chodorow, & Tetreault, 2008;Nesselhauf & Tschichold, 2002;Rezaee, Marefat, & Saeedakhtar, 2015;Shei, 2008;Shei & Pain, 2000;Wu, Witten, & Franken, 2010). Idiomatic expressions like to feel under the weather or to see eye to eye also appear to be particularly challenging for L2 learners (Ahmadi, Sahragard, & Babaie Shalmani, 2017;Cie slicka, 2006;Conklin & Schmitt, 2008;Steinel, Hulstijn, & Steinel, 2007;Wray, 2000), but have received less attention in CALL.…”
