Learn Hardcore German: Die Katze isst Brot.

Katze is grammatically feminine in German, so it always takes the feminine article die in the singular nominative case. Even if the actual cat is male, the word still remains feminine grammatically.

Why do we write "isst" instead of "ist"?

Although they look similar, ist (with one 's') is the third-person singular form of sein (to be), while isst (with two 's') is the third-person singular form of essen (to eat).

Why is "Brot" not preceded by an article?

In many German sentences, mass nouns like Brot (bread) can appear without an article when referring to an unspecified amount. It's common in situations where you're just saying someone is eating some bread, rather than specific bread.

How do I know "Brot" is the direct object (accusative)?

In German, the direct object typically follows the verb and often takes the accusative case. Since die Katze is the subject (nominative case doing the action), Brot must be the direct object that is being eaten.

Could I rearrange the word order in this sentence?
