"You have an apple, bread and water."
Translation:Macie jabłko, chleb i wodę.
"mieć" (to have) takes the Accusative case, which is "wodę".
Neuter nouns (like "jabłko") have Accusative the same as Nominative (the basic, dictionary form), and masculine inanimate nouns (like "chleb") also have those cases identical. But still you should be aware what case is this.
