The Latin sentence is: Marcus, qui erat in villa, librum dedit filio amici
Marcus, who was in the house, gave a book to his friend’s son
- Nominative Case
- Marcus: The nominative case is used for the subject of the sentence. The subject is the person or thing doing the action.
Here, Marcus is the subject because he is the one doing the verb – giving the book.
- Accusative Case
- librum: The accusative case is used for the direct object of the sentence. The direct object is the thing being acted on, or having the verb done to it.
Here, librum (book) is the thing being given.
- Genitive Case
- amici: The genitive case shows possession. It is often translated as “of” or with an apostrophe (“‘s”).
Here, amici means “of the friend.” It tells us that the son (filio) belongs to the friend.
- Dative Case
- filio: The dative case is used for the indirect object. The indirect object is the person receiving or benefiting from the action.
Here, filio (son) is the person Marcus is giving the book to.
- Ablative Case
- in villa: The ablative case is often used to show location, time, or means. When it is paired with a preposition like in, it often shows where something happens.
Here, in villa means “in the house,” telling us where Marcus was.
