Questions & Answers about Nasza lodówka jest pełna.
Why is pełna in the nominative case here instead of the instrumental case?
When using the verb być (to be) to describe a noun with just an adjective, the adjective stays in the basic nominative case. You only use the instrumental case if you are connecting the subject to another noun (like in Ona jest dobrą kobietą - She is a good woman). Since pełna (full) stands alone in this sentence, it stays nominative.
How do nasza and pełna match the word lodówka?
Lodówka is a feminine noun because it ends in -a. Therefore, the possessive pronoun for "our" must take its feminine form, nasza (instead of the masculine nasz or neuter nasze). The adjective pełna (full) also takes the feminine -a ending so that all three words agree in gender.
If I wanted to say the fridge is "full of food," how would I add "of food" to this sentence?
The word pełna (full) requires the noun that follows it to be in the genitive case. Because the nominative word for food is jedzenie, "full of food" becomes pełna jedzenia. You don't need a separate Polish word for "of" because the genitive case ending does that job for you!
