My question is about the infinitive without zu. I have learned that modal verbs take the infinitve without zu. So how is it possible that "Willst du etwas zu essen" is correct? Is it maybe because of the word "etwas"? Because we don't say "Willst du zu essen", we say " Willst du essen?" Right
Willst du etwas essen means Do you want to eat something? Willst du etwas zu essen means Do you want something to eat? Willst du etwas zu Essen? Willst du etwas zum Essen?
