Prepositions & the Accusative
Everyday Greek prepositions all GOVERN THE ACCUSATIVE: the noun after them takes the same object case you met in Module 2, so there are NO new endings to learn - you reuse the accusative article + noun forms you already know. Four high-frequency prepositions cover most needs: με (“with”), από (“from”), για (“for”), and χωρίς (“without”) - με τον φίλο, από την πόρτα, για τη μητέρα, χωρίς νερό. One of them does double duty: από also means “than” in a comparison - μεγαλύτερος από εμένα (“bigger than me”) - the very “than” you met when forming comparatives. (Even a pronoun after a preposition goes accusative: από εμένα, not *από εγώ.)
The rule
The everyday prepositions all govern the accusative, so there are no new endings to learn - you reuse the accusative article and noun you already have. Four cover most needs: με (“with”), από (“from”), για (“for”) and χωρίς (“without”) - με τον δάσκαλο, από την πόρτα, για τη μητέρα, χωρίς νερό. A pronoun after a preposition goes accusative too, and takes the strong form: από εμένα, never «από εγώ» and never the weak μου. One of the four does double duty: από also means “than” in a comparison - μεγαλύτερος από εμένα - the very “than” you meet when forming comparatives. And σε is the fifth, hiding in plain sight: before the article it never appears uncontracted, showing up as στον / στη(ν) / στο instead.
