This article provides introductory, step-by-step explanations of how to make a specialized corpus and an annotated frequency-based vocabulary list. One of my objectives is to help teachers, instructors, program administrators, and graduate students with little experience in this field be able to do so using free resources. Instructions are first given on how to create a specialized corpus. The steps involved in developing an annotated frequency-based vocabulary list focusing on the specific word usage in that corpus will then be explained. The examples are drawn from a project developed in an English for Academic Purposes Nursing Foundations Program at a university in the Middle East. Finally, a brief description of how these vocabulary lists were used in the classroom is given. It is hoped that the explanations provided will serve to open the door to the field of corpus linguistics. [Note: The issue number (11) shown on this PDF is incorrect. The correct citation is v34 n1.]
