The UNU Jargon Buster is a glossary app that clarifies hundreds of UN terms and acronyms, as selected by seven UNU sites: in Belgium (UNU-CRIS), Germany (UNU-EHS and UNU-FLORES), Iceland (UNU-GEST), Japan (UNU-IAS), Malaysia (UNU-IIGH), and the Netherlands (UNU-MERIT – the lead institute).

As of April 2016, UNU is also working on specific terminology from the International Organization for Migration (IOM), the Organisation for Economic Co-operation and Development (OECD), the UN Institute for Disarmament Research (UNIDIR), the UN Industrial Development Organization (UNIDO), the UN Office for Project Services (UNOPS), and the UN Research Institute for Social Development (UNRISD), among others.

This free app is a searchable, offline, one-stop shop: designed for anyone seeking a UN glossary anywhere in the world, at a conference or in the field, be they students, scholars or policymakers. It was compiled at UNU-MERIT in the Netherlands by Howard Hudson, Diego Salama and Iulia Falcan, with design and technical support from Mediablenders. It is intended only for information purposes. The inclusion of an item should not be construed as an endorsement by the United Nations University of any particular position, entity or programme.
