Questions & Answers about Dziadek ma dobrą pamięć.
Because pamięć is the direct object of the verb ma (has), so it goes in the accusative case.
- nominative: dobra pamięć = good memory
- accusative: dobrą pamięć = a good memory / good memory as the thing someone has
Since dobra describes pamięć, the adjective also has to change to match the noun in gender, number, and case.
For feminine singular nouns like pamięć, the accusative ending of the adjective is often -ą:
- dobra → dobrą
Because pamięć is a feminine noun whose accusative singular looks the same as its nominative singular.
So:
- nominative: pamięć
- accusative: pamięć
This is very common with many feminine nouns that do not end in -a. The adjective changes visibly, but the noun itself may stay the same.
