Pronouns and determiners play a crucial role in the Croatian language as they provide information about the nouns they modify or replace. Pronouns are used to replace nouns in a sentence, while determiners help to specify or quantify the noun they accompany.

Croatian pronouns include personal pronouns (ja — I, ti — you, on/ona/ono — he/she/it), possessive pronouns (moj — mine, tvoj — yours, njen — hers), demonstrative pronouns (ovaj — this, onaj — that), and interrogative pronouns (tko — who, što — what). They agree in gender, number, and case with the noun they replace.

Determiners in Croatian include articles (definite — the, indefinite — a/an), possessive determiners (moj — my, tvoj — your, njen — her), demonstrative determiners (ovaj — this, onaj — that), and quantifiers (malo — few, mnogo — many). They also agree with the noun in gender, number, and case.

Understanding pronouns and determiners is essential when learning how to form coherent sentences and properly modify nouns in Croatian.
