The Nuffic Glossary is a list with explanations of terms used in Dutch education.
In the context of Dutch development cooperation this is understood to be the organisation, educational institution or individual in a developing country who is supposed to benefit from a relationship with a Dutch partner. The word does not carry this connotation in English.
It simply means a comparable body: for example, DAAD is the German counterpart of Nuffic. 'Partner in the South' might therefore be a better choice. (N.B.: In development jargon, what used to be called the First and Third Worlds is now called 'North' and 'South'.)
