dinterès

D’interès is a Catalan expression meaning “of interest” or “of relevance.” It is formed by the preposition d’ (of) and the noun interès (interest). The standard spelling uses the apostrophe: d’interès. In informal writing or branding you may encounter the unspaced form dinterès, but this is nonstandard in formal Catalan.

Etymology and sense: Interès comes from the Latin interesse, passing through Old Catalan and other Romance languages, with meanings that include concern, stake, benefit, and later financial interest. The particle d’ denotes relation or belonging, so d’interès marks something as being of interest or importance to someone or a group.

Usage: The phrase d’interès is used to qualify nouns to express relevance or appeal. Common collocations include tema d’interès públic (a topic of public interest), projecte d’interès local (a local-interest project), and qüestions d’interès científic (scientific-interest issues). In economic or financial contexts interès may refer to money charged or earned, as in tipus d’interès (interest rate); in such cases the noun interès retains the financial sense, and the prepositional construction can still appear when describing related objects.
