The Use of the CTTR Index in Lexical Diversity Analysis of RFL Students̕ Interlanguage

Abstract

The transitory nature of interlanguage, seen as a temporary linguistic system of a foreign language learner, requires the use of methodologies that go beyond the narrow framework of compliance with the norm. In this article, we aim to present a methodology for analyzing the lexical diversity of interlanguage, using the CTTR index. We will also present the results of a pre-test that applies this approach to the language production of international RFL students.
