Questions & Answers about Das ist der Fehler eures Modells.
Why do we say eures Modells instead of just euer Modell?
This is the genitive case, which shows possession or belonging. Instead of using a preposition to say "the error of your model", German changes the endings of the words to show that the error belongs to the model.
Where does the word eures come from?
The base word is euer, which is the possessive article for "your" when talking to a group of people informally (plural "you"). Because das Modell is a neuter noun, euer takes the neuter genitive ending -es to become eures.
Why is there an extra "s" at the end of Modells?
In the genitive case, masculine and neuter nouns almost always add an -s or -es to the end of the word. Since das Modell is neuter, it gets an -s added to become Modells.
Why is it der Fehler and not den Fehler? Isn't it the object of the sentence?
The verb sein (here as ist) acts like an equals sign and connects two things. It always takes the nominative case, never the accusative. So, der Fehler stays in its original nominative form.
