tvojmu
"Tvojmu" is a possessive pronoun in the dative case used in the Czech language. It is the dative form of the possessive adjective "tvůj," which translates to "your" in English. The dative case in Czech is used to indicate the indirect object of a sentence, the recipient of an action, or the person to whom something is being done. For example, "Dám knihu tvojmu příteli" translates to "I will give the book to your friend." The dative case is one of the seven cases in the Czech declension system, which is used to indicate the grammatical function of a noun or pronoun in a sentence. The possessive pronoun "tvojmu" is used to show ownership or association with the person being referred to, and it agrees with the gender and number of the noun it modifies.
