One of my books is “Introduction to Attic Greek” by Mastronarde, and in Unit 3 he begins his explanation of the Greek cases. I have a basic question on the genitive case, and I’ll use the word “road” that he gave in an example. His example merely enumerated the case endings for singular and plural, and did not give an an example of how each case would show up in a sentence.
My question involves knowing when a noun takes the genitive case. For example, making up a sentence, “The boy likes to play in the road of my father.”, would it be correct to say that “road” in this case is not genitive, but accusative?
On the other hand, in the sentence, “Ten feet is the width of the road”. Would it be correct to say that “road” takes the genitive case here?
I’m using “of the” phrasing because, as I understand it, the english convention of 's does not have a direct representation in Greek. In the first example, internally I was thinking of the english equivalent “father’s road” (hence, “road” is not genitive), and in the second example, I was thinking of the english equivalent “road’s width” (making road genitive).
I only know about 4 Greek words at this point, and am only just getting into a definition of the cases. I’m aware that my question is extremely basic (even trivial?), but I’m operating without the aid of an instructor, and I’m afraid of getting off on the wrong foot by assuming something that is incorrect.
