Questions & Answers about Dyrektor ma dużo planów na jutro.
Why does the word planów have the -ów ending?
Planów is the Genitive plural form of the masculine noun plan. Because it ends in a hard consonant (n), its Genitive plural ending is -ów. This is the standard ending for most masculine nouns in this case.
Why do we need the Genitive case here anyway? Why not just say dużo plany?
In Polish, words expressing quantity or amount, like dużo (a lot) or mało (a little), force the following noun to take the Genitive case. Because you are saying a lot of something, plany (Nominative) must change to planów (Genitive).
Could I use wiele instead of dużo in this sentence?
Yes, you could say Dyrektor ma wiele planów na jutro. Both dużo and wiele mean "many" or "a lot" in this context, and both require the following noun to be in the Genitive case.
Why do we use na before jutro?
The preposition na is used here to indicate a time frame for a plan or arrangement. When used this way, it takes the Accusative case. Since jutro (tomorrow) is naturally an adverb, it doesn't change its form when treated like a noun in this phrase.
