this is not really German so don't use this to learn German.
the = der (boy)
the = die (girl)
the = das (anythings else)
you say it with a german voice with the same type of thing E.g. winter is said with a v not a w so say it like this: vinter.
when talking about animals and you want it to have a gender then write
'the girl cat' = die cat.
