ádném

ádném is not a standalone standard word in Czech. It is best understood as the locative singular inflection of the determiner žádný, used after prepositions that require the locative case. In standard orthography the full form includes the initial ž, written as žádném. For example: v žádném domě (in no house), v žádném případě (in no case), o žádném jídle (about no food). The function is to express negation or absence within a specific context.

In Czech, žádný behaves as a negative determiner that agrees with the noun it modifies. Its principal inflected forms include žádný (nominative masculine), žádného (genitive), žádnému (dative), žádným (instrumental), and žádném (locative). The lexeme is used to negate existence or quantity, similar to how English uses "no" or "none" in phrases like "no time" or "no thing."

Orthographic note: ádnem without the initial ž is not standard; such a form is typically a misspelling or typographical error rather than a recognized word in Czech. When seen in text, it should be read as a corrupted writing of žádném or corrected to žádném depending on the context.

Etymology generally traces žádný to the negative determiner family in Czech, historically related to the interrogative jaký (which). It functions as a determiner and pronoun in various negated noun phrases, declining across gender, number, and case as described above.
