Possessivními

Possessivními is the instrumental plural form of the Czech adjective possessivní, meaning "possessive." It is used to modify a noun or a noun phrase in the instrumental case, typically after prepositions that require instrumental, such as s (with). In Czech, adjectives inflect for gender, number and case; for the instrumental plural, possessivní takes the ending -ými, matching the accompanying plural noun.

Usage and examples: The form is used whenever the possessive adjective describes something in the instrumental plural context. Common examples include s vašimi knihami (with your books), s našimi kamarády (with our friends), or with pronoun-based possessives in plural contexts, such as s mými sestrami (with my sisters). The construction generally expresses possession or association within a phrase governed by the instrumental case.

Relation to other forms: Possessivní is part of a broader system of Czech possessive expressions, which also includes Přivlastňovací zájmena (possessive pronouns) and Přivlastňovací determinativa. While possessivní describes attributes of nouns, possessive pronouns function as independent words that carry ownership. In many contexts, the two systems overlap in their endings, especially in instrumental plural.

Grammatical notes: Like other adjectives, possessivní declines according to gender, number and case. The instrumental plural form possessivními is one of the standard endings used in everyday Czech to indicate possession in phrases requiring the instrumental case. Mastery of these forms aids in correct agreement in complex noun phrases and with prepositional constructions.
