Why does Gross mean large but not big?
In general groß means also big. It depends on the context if it should be accepted or not. Here it's fine, I think. I would probably call it a large coat.
It can be both, and when describing a person, it usually means TALL!
The "Mein Mantel ist kurz" and "Mein Mantel ist groß" sentences are very similar and misleading
My coat is large/small is misleading? They're two different sentences with different meanings.
I cannot tipe that letter
Why not "huge"?
