Oficiálním
Oficiálním is a Czech adjective derived from the word "oficiální," meaning official. It functions as the genitive, dative, or accusative masculine singular form of the adjective, indicating possession, indirect object, or direct object in relation to a male noun. For instance, "oficiálním dokumentem" translates to "of the official document" (genitive) or "with an official document" (instrumental, though the question asks for genitive, dative, or accusative). In the dative case, "oficiálním dopisem" would mean "to an official letter." As an accusative, "viděl jsem oficiálním vlakem" would mean "I saw the official train." The adjective describes something that is authorized, sanctioned, or recognized by an authority or government. It implies formality and adherence to established rules or procedures. The concept of "oficiálním" is central to understanding legal documents, governmental processes, and formal communications within the Czech Republic and other Slavic languages where similar grammatical structures exist. Its usage signifies a level of authority and legitimacy that distinguishes it from unofficial or informal matters.
