Example
Dem
dritten Mann hat er ein Buch geschenkt.
= He gave a book to the third man.
Mann is masculine.
There is a definite article (dem)
and it is Dativ. If we check the corresponding table we see that the ending (better the grammatical morpheme) is -en.
Another example
Ein
drittes Mal wird es nicht geben. = There will be no third time.
Mal is neutral. In this case there is an indefinite article (ein)
and it is Akkusativ. If we check the corresponding table we see that the ending (better the grammatical morpheme) we have to use is -es.
And yet another example
Das war mein
drittes Bild. = This was my third picture.
Bild is neutral. Now we have a possessive pronoun (mein)
and it is Nominativ. If we check the corresponding table we see that the ending (better grammatical morpheme) was have to use is
-es.
