I was under the impression somehow that the Greek really would consist of three words:
willwork not flashlightofyou.
That's where you tripped up. "flashlight" and "you" serve different functions in the sentence and they would be two separate words in two different cases. Flashlight
is nominative because it's the subject; you
is genitive, because it's possessive. Flashlightofyou
is an impossible construction in Greek.
is possible to use in the genitive, as in "I'm not going to pay for half of a flashlight!" In Greek, I
would be in the nominative (or implied in the conjugation of the verb), am going to pay for
would be a 1st person singular future active indicative verb, not
would be the negative particle, half
would be the accusative direct object and of a flashlight
would be a noun in the genitive, modifying and limiting half
Does this make the cases any clearer?
