Zainteresowani

Zainteresowani is a Polish term that can function as an adjective meaning “interested” or as a noun phrase referring to people who have an interest in something. In formal contexts, especially in law, public administration, and planning, it designates stakeholders or parties with a direct legal or factual stake in a decision, action, or outcome. In everyday language it can simply mean “those who are interested” in a topic.

Grammatically, zainteresowani is the masculine plural form of the adjective zainteresowany. The feminine plural form is zainteresowane, and the neuter form mirrors that pattern. The word is derived from the verb zainteresować (to interest), itself connected to the concept of interest or concern.

Usage examples include legal and administrative texts where one speaks of “strony zainteresowane” (the interested parties) or “zainteresowani projektem” (those interested in the project). In non-legal contexts, it can describe someone who is keen on a subject, as in “zainteresowani kulturą” (people interested in culture). The term is often paired with nouns to specify the context of interest, such as postępowaniem (proceedings), projektem (project), or ustawą (law).

Related terms include zainteresowanie (the noun for interest or concern) and zainteresowany (the masculine singular adjective meaning “interested”). In contemporary Polish, the English loanword interesariusz or interesariusze is also used in business contexts to denote stakeholders, but zainteresowani remains common in formal and legal language.
