ustalona

Ustalona is a feminine form of a Polish adjective and past participle meaning established, fixed, or determined. It is used to describe information or arrangements that have been decided or agreed upon. The word commonly modifies a feminine singular noun, as in ustalona data (the established date) or ustalona zasada (the established rule). In broader contexts the concept applies to masculine or neuter forms and to plural nouns as well (for example, ustalony plan, ustalone warunki).

Etymology and formation: ustalona derives from the verb ustalać (or its perfective counterpart ustalić), which means to establish, determine, or fix. As an inflected form, ustalona agrees with the gender and number of the noun it modifies.

Grammatical notes and usage: as a past participial adjective, ustalona typically appears in nominal phrases indicating that something has been set or agreed. It is common in formal and semi-formal registers, including administrative, legal, and policy contexts, as well as in journalistic or descriptive writing. Typical constructions include ustalona data, ustalone zasady, and inne ustalone warunki. The corresponding masculine form is ustalony, the feminine neuter form is ustalone, and the plural forms adapt to the noun.
