In Danish grammar, personal pronouns are essential for constructing sentences to communicate thoughts, desires, and actions. They are used to refer to the subject in the sentence, often replacing a noun to avoid repetition. This exercise focuses on Danish personal pronouns, including jeg (I), du (you), han (he), hun (she), den/det (it), vi (we), I (you plural), and de (they). Practicing personal pronouns in Danish will help build a strong foundation in speaking and understanding the language.
