Questions & Answers about Do tej pizzy potrzebuję tylko pół szklanki mąki.
Why are both szklanki and mąki in the Genitive case?
Pół (half) acts like a quantity word, so the noun right after it must be in the Genitive case, changing szklanka (glass) to szklanki. Then, to say a glass OF flour, we need the Genitive again, changing mąka (flour) to mąki.
Does the verb potrzebować (to need) affect the case of pół szklanki?
Potrzebować usually forces the thing you need into the Genitive case. However, pół is a special, unchangeable word. It stays as pół no matter what the verb requires, and then it forces the noun following it into the Genitive case anyway!
Why does ta pizza change to tej pizzy at the start of the sentence?
The preposition do (meaning 'for' in this context) always requires the Genitive case. So, the feminine word ta (this) changes to tej, and pizza changes to pizzy.
How does Polish treat a borrowed word like pizza?
Even though it is an Italian word, Polish treats it just like a standard feminine noun because it ends in -a. It keeps the original 'ts' sound in the middle, and you simply swap the -a for a Polish -y sound at the end for the Genitive case.
