unió

Unió, in Catalan, is a noun meaning the act of joining two or more elements into a single entity, or the result of such joining. It is used across a range of contexts to denote unity, alliance, or fusion, including political, mathematical, legal, and social domains. In everyday language it can refer to any form of coming together, from marriages and partnerships to coalitions and federations.

Etymology and orthography

The word derives from Latin unio, unionis. In Catalan it is written unió, with a diaeresis over the i in older forms and now an acute accent on the i to indicate stress. Its plural form is unions.

Uses in politics and society

In politics, unió frequently appears in the names of coalitions or parties, and as a generic term for alliances. The best-known example in Catalan politics is Unió Democràtica de Catalunya (UDC), a historical Catholic-conservative party that participated in broader center-right coalitions. More generally, unió can describe any formal pact or federation, such as the unió of municipalities or regional governments.

Mathematical and linguistic usage

In mathematics and logic, unió denotes the union of sets—the operation that combines all elements that belong to either of two or more sets. In civil and social language, the term can evoke the idea of unity within a community, a nation, or between individuals.
