Corpus linguistics is one of the fastest-growing methodologies in contemporary linguistics. It utilizes a large and principled collection of natural texts, known as a corpus, as the basis for nalysis. At the same time, corpus linguistics is more than a methodological approach, because it has enabled researchers to ask fundamentally different kinds of research questions, sometimes resulting in radically different perspectives on language variation and use from those taken in previous research. And to make good use of corpus resources one needs a modest orientation to the routines involved in retrieving information from the corpus, and most importantly training and experience in how to evaluate that information. Hence, this paper presents corpus techniques in the field of teaching addressing the possible areas of its usage in vocabulary development through some activities requiring quantitative and qualitative analyses.
