I'm learning German and I struggle with making words agree. I want a website where I can put in something like
"der sehr groß Mann" (wrong)
and it will inform me that it should be (I think)
"der sehr große Mann" (right in Nominativ)
also perhaps with the possibility of specifying what case I am using this phrase in, because if it's in Akkusativ then it should instead be
"den sehr großen Mann" (right in Akkusative)
Does this kind of thing exist?
