nepátelskou

Nepátelskou is the instrumental feminine singular form of the Czech adjective nepřátelský, meaning unfriendly or hostile. In standard Czech, the instrumental feminine singular form is nepřátelskou; the spelling nepátelskou is generally considered a misspelling or a nonstandard variant, potentially arising from omission of diacritics or confusion with similar-sounding forms.

Grammatical use and examples: Nepřátelský forms take various inflections to agree with the noun they modify. Nepátelskou (intended as nepřátelskou) is used to describe a feminine noun in the instrumental case, for example after certain prepositions or in predicative constructions. Examples include Vztah s nepřátelskou stranou byl napjatý (The relationship with the unfriendly side was tense) or Atmosféra nepřátelskou atmosférou se vyznačovala (The atmosphere was characterized by an unfriendly mood).

Etymology and nuance: The form is built from ne- (negation) plus přátelský (friendly), yielding unfriendly. It contrasts with nepřátelský in the masculine form and nepřátelská in the feminine nominative. The instrumental nepřátelskou emphasizes the manner, atmosphere, or relation being unfriendly. In standard usage, nepřátelskou is the correct instrumental feminine form; nepátelskou is typically seen as a misspelling or rare variation.
