interessada

Interessada is the feminine singular form of the Portuguese word related to interest. It can function as an adjective or as a noun. As an adjective, interessada describes someone who has interest in something, for example: “Ela está interessada no projeto.” As a noun, “a interessada” refers to a person who has a stake, concern, or legitimate interest in a matter. The masculine counterpart is “interessado.”

Usage in everyday language is broad. A person may be described as interessada simply because they are curious or fond of something. In formal contexts, especially in law, business, and public administration, interessada commonly denotes a party with standing or a stakeholder in a dispute, transaction, or procedure. Phrases include “parte interessada” (interested party), “pessoas interessadas,” or “interessadas no processo.”

The term often implies more than mere curiosity; it signifies a recognized interest that may grant rights, responsibilities, or participation in a process. For example, in a contract or regulatory proceeding, the partes interessadas are informed and may have a voice or veto rights depending on the regime.

Etymology: interessada derives from the verb interessar, which in turn comes from Latin interesse (to be of importance, to matter), formed with inter- plus esse. The feminine form arises from gender inflection in Portuguese.
