... Several researchers and SLA scholars (Liu, 1999;Yuan & Lin, 2001;Lien, 2003;Shormani, 2012a;Shormani &Sohbani, 2012) argue that collocation knowledge helps L2 learners have a good command on communication and develop a native-like proficiency. However, lexical error studies are relative few compared to those done on other types of errors such as syntactic, phonological, morphological, etc. (Tomasello, 2007;James, 1998;Han, 2000, Cook, 2003Taylor, 1976;Gass&Selinker, 2008;Laufer, 1986Laufer, , 1990Laufer, , 1997, fewer are those studies tackling collocation errors (Shormani, 2012a, 2012b, Shormani &Sohbani, 2012Rababah, 2003;Zughoul, 1979;Mukattash, 1979Mukattash, , 1981Mahmoud, 2005Mahmoud, , 2011Wray, 2000;Taylor, 1986) and fewest, if any at all, are those deeply probing the sources of such errors and their consequences (Shormani &Sohbani, 2012;Mahmoud, 2005). This is due to two major reasons: the first is the fact that studying collocation errors and probing deeply their sources is much challenging and complicated for their nature and what information they involve in addition to the difficulty in assessing them. ...
