I. Theory
The dative case is used to show the indirect object of the sentence. In English, indirect objects are usually separated from the verb acting on them by a preposition ‘I wrote to her’. The indirect object can also show to whom or for whom the verb is acting:| I gave the notes (direct) to you (indirect). He bought you (indirect) this gift (direct). |
In German, this case is shown through article declensions unlike in English where only prepositions or context are used to show the indirect object.
