Questions & Answers about Der Himmel ist heute grau.
Wait, since Himmel is masculine, shouldn't the adjective be grauer?
No, because grau is used here as a predicate adjective (an adjective that describes the subject but comes after a linking verb like sein). In German, adjectives only get declension endings when they come directly before a noun, like in ein grauer Himmel (a grey sky).
Can I change the word order to put heute at the beginning of the sentence?
Yes, you can absolutely say Heute ist der Himmel grau. Remember the strict "verb second" rule in German main clauses: the conjugated verb (ist) must stay in the second position. When you move heute to the first spot, the subject (der Himmel) gets bumped to the third spot right after the verb.
Does Himmel always mean "sky"?
No, Himmel can mean either "sky" or "heaven" depending entirely on the context. In everyday conversations about the weather, like noting that it is grau (grey) or blau (blue), it means "sky".
