Step-by-step explanation:
So, a lot of words in German are either masculine, feminine, or neuter [neither].
These different genders correspond to different articles [different ways to spell the, or a, etc.]
It's honestly random for if a lot of words are masculine/feminine/neuter, and you just have to remember a lot of them.
Some words, like woman / man , daughter / son, etc. are easy to guess (just use the actual gender of the noun)
When words are feminine, we use:
die, eine
When words are masculine we use:
der, ein
When nouns are neutral, we use:
das, ein
there are many other articles, but these are a good few examples.
{Note: the article does change according to the case of the noun, like accusative [Akkusativ] or nominative [Nominativ]. Sometimes "ein" might be "einen", and I'm sure your teach will teach more about this in future German lessons :) }
hope this helps!! :)
