Language Learning

Wanted to ask for some tips since I'm really struggling with this trying to learn German.

I know there are certain ways to guess the gender (e.g. -er endings are usually masculine, -ung feminine and loan words neutral) but often times I'm just butchering the whole sentence by not knowing the correct articles.

Let me demonstrate my frustration: in many cultures the moon is considered "feminine", but in German it has masculine article!
