Definite articles

German nouns are often preceded by an article.

The article indicates the case, number and gender of the noun it precedes.
There are definite and indefinite articles.

A definite article refers to an object or person whose identity is already known to the speaker or listener.

German has three classes of gender: masculine, feminine and neuter.

    Definite article      Noun
Masculine      der   Fahrer
Feminine   die   Katze
Neuter   das   Taxi

Important note!
Unfortunately there's no general rule for articles. You have to learn the gender of each noun by heart. The nouns in your vocabulary list are shown with their articles, so always learn both: the noun and the article that goes along with it!

 

More:

For all three genders - masculine, feminine and neuter - the definite article in the nominative plural is always "die".
