"Other studies, such as those of Santos (1984), Horowitz (1986), and Johns (1981) also endeavored to investigate the characteristics of L2 discourse and text that were perceived to be essential in the evaluation assessment of NNS writing among the faculty in various departments, including English. Their results indicate clearly that the expectations of faculty remain consistently focused on lexicogrammatical features of text, such as sentence structure, vocabulary, the syntactic word order, morphology/inflections, verb tenses and voice, and pronoun use, as well as spelling and punctuation." - Hinkel (2002)
So, when Ss come to English-medium universities already having learned English in an ESL/EFL country, and their usage includes variations (which may or may not be systematized 'at home') -- then what? Is this a place where WEs and L2 writing can overlap?
