Please note that this version is still undergoing development and refinement. Your feedback is greatly appreciated.

UNTERM is a multilingual terminology database maintained jointly by the Secretariat (including the main duty stations and regional commissions) and certain specialized agencies of the United Nations system, including the International Maritime Organization, the United Nations Educational, Scientific and Cultural Organization, the World Health Organization and the World Meteorological Organization.


UNTERM provides terminology and nomenclature in subjects relevant to the work of the United Nations system. Information is provided in the six UN official languages, and there are also entries in German and Portuguese.


This database is a linguistic tool created primarily to facilitate the work of staff of the United Nations system and other people around the world who participate or are interested in the Organization's activities. The inclusion of an item in this database should not be construed as an endorsement by the United Nations of any particular position, entity or programme.


Some entries in this database are very recent while others may have been retained for historical reasons. Please let us know in the Feedback form of any mistakes, discrepancies or missing data. We will be grateful for your input.
