pocházejícího

pocházejícího is the genitive singular masculine/neuter form of the present active participle of the Czech verb pocházet. Pocházet means "to come from," "to originate from," or "to stem from." Therefore, pocházejícího is used to indicate possession, origin, or relationship in the genitive case for a masculine or neuter noun that is performing the action of originating.

For example, if you were to say "the book originating from the library," in Czech it would be "kniha pocházejícího z knihovny." Here, "pocházejícího" modifies "knihovny" (library) and indicates that the book's origin is the library. Similarly, "the man originating from Prague" would be "muž pocházejícího z Prahy."

The use of the genitive case after prepositions like "z" (from) is common in Czech, and the participle agrees in gender, number, and case with the noun it describes or modifies. Thus, pocházejícího specifically refers to a masculine or neuter singular entity that is the source or origin of something. Understanding this grammatical form is crucial for accurate comprehension and construction of Czech sentences involving origin or provenance.
