During the past decade, the financial and economic crisis has been one of the most discussed subjects, and, consequently, its impact in every level. This research focuses on the most relevant terms of this crisis, and particularly on the terms related to the Greek financial crisis. The starting point of our research is a glossary consisting of 800 entries, with their equivalents in various languages. Our objective is to verify the occurrences in corpora of these terms in three languages (French, English, Greek), to study their frequencies and to describe their behavior in context. Corpora allow the validation of terms that are not yet established, standardized or included in terminological databases and reference resources; moreover, we can extract and list the variations of equivalent terms. Our approach aims to complete and enrich the existing glossary, and to offer a useful tool for both translators and technical writers.
