któremu

Któremu is the dative singular form of the Polish relative pronoun który. It is used to introduce a relative clause and refers to a masculine or neuter antecedent. In the relative clause, the form of the pronoun depends on the syntactic role it plays there, typically governed by the verb or preposition in that clause.

In Polish, کی forms of the relative pronoun change with gender and case. The form który has a dative singular form któremu, which appears when the relative clause contains a verb or expression that requires the dative case. For feminine antecedents the corresponding form is która or której, and for plural antecedents forms such as którym may be used. The key point is that który’s forms adapt to the grammatical needs of the relative clause rather than the main clause’s structure.

Usage and examples:

- To jest człowiek, któremu ufam. (This is the man whom I trust / to whom I trust.)

- Znałem człowieka, któremu pomogłem. (I knew a man to whom I helped.)

- To miejsce, któremu nic nie zawdzięczamy. (That place to which we owe nothing.)

Któremu is common in written and spoken Polish when the referent of the relative clause is masculine or neuter and the clause requires a dative object. It is part of a broader system of relative pronouns based on depends on person and case, with feminine and plural forms differing.
