Remebering “one of these” in German
I used to get really confused about how to say this in German (”one of the/one of the(o)se”) because of what ending to use but it’s legit so simple - e.g.
Einer dieser Steine = One of these stones.
 = The plural form of the final word, super easy (e.g. stones/Steine).
 = This always ends er because it’s genitive plural - thus dieser/der.
 = This is the bit that throws people, it’s declined like “dieses”, but if that’s too much thought just find the gender of the plural word + add the ending of its definite article - e.g. deR Stein
diE Katze = Eine dieser Katzen.
daS Haus = Eines dieser Häuser
Like honestly I can’t believe how simple it is after all of the confusion I’ve had :/
