otvorený

Otvorenú is a feminine singular accusative form of the Slovak adjective otvrený (written with proper diacritics as otvorený in masculine, otvorená in feminine nominative, and otvorené in neuter). It means open or opened and is used to describe a feminine noun in the accusative case. In practice, it appears in phrases such as otvorenú knihu (an opened book) or otvorenú obálku (an opened envelope). The form reflects Slovak agreement rules for adjectives and participles: the base stem otvoren- comes from the verb otvoriť (to open), and the ending -ú marks feminine singular accusative.

Etymology and usage: otvorený derives from otvoriť and functions both as a past participle and as a descriptive adjective. It can denote physical openness, as in doors, envelopes, or files that have already been opened, and it can carry figurative senses, such as openness to ideas or opportunities when used in broader constructions (for example, otvorená spoločnosť, though the exact case form depends on the sentence). The word often appears in written Slovak, news reporting, and descriptive prose.

Grammatical notes: As with other Slovak adjectives, otvorenú must agree with the noun it modifies in gender, number, and case. The feminine accusative form is used when the noun is feminine singular and functioning as the direct object of the sentence. Other forms of the same adjective include otvorená (nominative feminine singular) and otvorené (neuter or plural forms), adapting to the grammatical context.
