piirkondadevahelise

Piirkondadevahelise is an Estonian adjective meaning interregional or between regions. It is formed from the words for region (piirkond) and between (vahe) with a suffix that yields an adjective, and it appears in the genitive singular form piirkondadevahelise when modifying a following noun, for example piirkondadevahelise koostöö, meaning interregional cooperation. The term is primarily used in official, policy, and academic language to describe activities, relationships, or policies that cross regional boundaries.

The main function of the term is to specify that an action or relationship spans more than one administrative or geographical region. It is commonly found in government planning documents, regional development strategies, statistical reports, and descriptions of European Union programs that focus on cooperation between regions. The phrase appears in contexts such as interregional projects, funding calls, and cross-regional initiatives, often preceded by prepositions like raames (within the framework of) or seoses (in connection with).

Usage notes: piirkondadevahelise is a neutral, technical descriptor and does not imply hierarchy or superiority among regions. It is typically used in formal language to distinguish activities that involve multiple regions from those that are intra-regional.
