Three Genders
Gender is often a difficult thing for language learners to master. The German language introduces a neutral gender as well as feminine and masculine. The neutral gender exists for words that the traditional genders don’t apply to.
The Long Words
German is well known for its long words. Its longest word is “Rindfleischetikettierungsüberwachungsaufgabenübertr agungsgesetz“, and it means” the law concerning the delegation of duties for the supervision of cattle marking and the labeling of beef.” It’s so long that the word is now obsolete. It was judged as being much too long and impractical for bureaucrats to even use.
Fraktur Script
German was written in a calligraphic script called Fraktur script. Fraktur is a Gothic script and is related to the Latin alphabet, it’s just a different type. It entered into use during the 1500s and was used all the way up until World War II.
