LanguageLearning

I am perhaps too old to answer that question, as I don't stumble upon new words often enough any more.

Most of the new ones for me are imported terms, like "Computer" or "Internet".
These are mostly gendered based on the translation of the part that defines them, e.g. "the net" - "das Netz", so it is somewhat logical.

There are some unclear or disputed ones, though. E.g. "Interface" is "das", but "API" (from application programming interface) often is "die", because "the interface" translates to "die Schnittstelle".

Also, there are some regional differences.
E.g. "Butter" is female ("die") in many parts of Germany, but in some it is male "der".

To sum up: It is complicated.

The recommended way for remembering words' genders is to always attach an adjective in front of a word when learning it.

Do not try to learn "die Nacht".
Learn "stille Nacht", which means "a quiet night".
The -e in the word "stille" is there because the word is feminine. When you learn "stille Nacht", you can automatically recognize it must be "die Nacht".
Similarly: "Blödes Auto" means "Stupid car". the ending -es means it's das Auto.
And "Blöder Mann" means "stupid man". -er, because it's der Mann.

Same works in other languages as well. Buen viño = Good wine. Therefore: El viño. Persona rapida = A fast person. -a means it's la persona.

Because a native speaker of German often hears adjectives in combination with words when they learn them, they automatically constantly receive the necessary information on the words' genders.
