CASE

Greek nouns have case, or different forms which express their relationship to other things.  The closest analogy in English are the different forms of pronouns:  “I,” which is used as a subject, is like nominative case in Greek; “my,” indicating posession, is like genitive; and “me,” an object, is like dative or accusative.  For example:  in Greek, to express the idea “of the ocean,” the genitive of  ὁ ὠκεανός would be used:  τοῦ ὠκεανοῦ.

The Greek cases are:
- nominative, or the subject of a verb;
- genitive, indicating posession or origin (like the use of “of” in English);
- dative, the indirect object of a verb, or location (like “to” or “for” in English);
- accusative, the direct object of a verb; and
- vocative, direct address.

Here are the cases of the singular form of the word ἄνθρωπος, “man”:

nominative   ὁ ἄνθρωπος (the man)
genitive   τοῦ ἀνθρώπου (of the man)
dative   τῷ ἀνθρώπῳ (to or for the man)
accusative   τὸν ἄνθρωπον (the man--direct object)
vocative   ἄνθρωπε (direct address; no definite article)

ὁ βίος τοῦ ἀνθρώπου thus means “the life of the man.”
