Finding the right gender of a noun
German articles are used similarly to the English articles,a and the. However, they are declined differently (change) according to the number, gender and case of their nouns.
In the German language, the gender and therefore article is fixed for each noun.
The most difficult part of learning the German language is the articles (der, die, das) or rather the gender of each noun. The gender of each noun in German has no simple rule. In fact, it can even seem illogical. For example das Mädchen, a young girl is neutral while der Junge, a young boy is male.
It is a good idea to learn the correct article for each new word together - even if it means a lot of work. For example learning "der Hund" (the dog) rather than just Hund by itself. Fortunately, there are some rules about gender in German that make things a little easier. It might be even nicer if these rules didn't have exceptions - but you can't have everything!

German nouns belong either to the gender masculine (male, standard gender) with the definite article der, to the feminine (feminine) with the definite article die, or to the neuter (neuter) with the definite article das.
