Can someone explain the different forms of "weiß" to me? I'm trying to figure out when they're meant to be used.
I'm also learning german and i am as lost as you are, but i have noticed a pattern: these changes have something to do with the gender of the word relative to the colour.
Ei, is neuter. The preposition for a neuter word is Das. Ends up in S. And so does the colour. WeißeS.
If it was a feminine word, which the preposition would be Die, who ends up in E. The colour would end up in E too: Weiße.
And if it was a masc. word, which the preposition would be Der/Den/Dem (depends on the case), the colour would end up in the same way: Weißer/Weißen/Weißem
This is how i've been addressing this stuff, and it's been working out so far. But i am not sure. If someone understand it any better please feel free to explain. =D
There are three different inflections: strong (with no definite article: die der das) weak (with a definite article) and mixed (indefinite article: ein kein or possessive: mein sein). You can find a very clear explanation with the complete table for the four cases here http://en.m.wikipedia.org/wiki/German_declension in Attributive adjectives. To end up: everything depends on gender, article and case.
This is my best shot at coming up with a way to memorize all of this.
