Questions & Answers about Wir kaufen heute frische Karotten.
Why does the adjective frische end with an -e here?
It describes the plural noun Karotten in the accusative (direct object) case. Because there is no article (like die or meine) in front of the noun, the adjective has to take the strong ending to show the case. For plural nouns without an article in the accusative case, we add -e.
Why is heute placed before frische Karotten? Can I put it at the end of the sentence?
While English usually puts time words at the end of a sentence, German prefers them early on. Adverbs of time like heute (today) typically come right after the conjugated verb and before the direct object (frische Karotten).
The English translation says 'are buying'. Why is there no German word for 'are' here?
German does not have a separate continuous tense like English does with its '-ing' verbs. The simple present tense verb kaufen means both 'buy' and 'are buying'. You never use a helping verb like sind to express an ongoing action.
