In a recent study, I have suggested that advanced L2 English data collected from naturalistic non-instructional settings and traditional learner essays are statistically significantly different when it comes to writers adopting various ongoing grammatical changes. In this paper I will test whether these quantitative and qualitative differences in the nature of the data can be attested through typological profiling which has previously been used to analyze learner varieties and indigenized world English varieties. This paper tests the typological profiling methods elaborated in Szmrecsanyi (2009) and Szmrecsanyi & Kortmann (2011) on advanced L2 English as represented in spoken ELF interactions in VOICE and in a written corpus of advanced L2 English that contains texts from a variety of text types on the informational-interactional continuum. This method measures grammatical analyticity, defined by the presence of free grammatical markers, and grammatical syntheticity, the presence of bound markers. It is expected that the results could shed light on the typological status of advanced L2 English and provide empirical evidence on possible qualitative and quantitative differences between traditional learner data and global English material collected from naturalistic settings.
