otvírací

otvírací is a Czech adjective that translates to "opening" or "open" in English. It is commonly used in various contexts to describe a state or action of being open.

In the context of hours, otvírací doba refers to an establishment's operating hours, indicating when it is open to the public. For example, "obchodní dům má dlouhou otvírací dobu" means "the department store has long opening hours."

The term can also describe a physical object that is designed to be opened. An otvírací nůž, for instance, is a pocket knife that can be opened. Similarly, otvírací láhev refers to a bottle that is meant to be opened, often implying it's a new or sealed one.

In a more abstract sense, otvírací can signify the commencement or initiation of something. An otvírací ceremoniál would be an opening ceremony.

The word is derived from the Czech verb "otevřít," meaning "to open." Its grammatical form changes depending on gender, number, and case to agree with the noun it modifies. For example, "otvírací doba" (feminine singular), "otvírací hodiny" (feminine plural, often used interchangeably with singular for hours), and "otvírací den" (masculine singular).
