In English, the word that can be used as emphasis for adjectives (with some prior context). For example:
I’m not that rich.
She’s not that dumb.
Is he that mad?
How can we use the same kind of emphasis in German?
Edit:
I know that can be translated as das, dass and diese. However, those aren’t what I’m looking for. Also, the that here refers to some level of the adjective that’s previously stated. It can be used without not too, and I’m not sure about so (German) since it doesn’t feel like what I’m looking for exactly.
Another example:
Is he so smart that he got a Nobel Prize?
Yes, he’s that smart.
