Pizza is _____ . however unhealthy, is still tasty.
(sry if the sentence is structured incorrectly, I’m still learning grammar).
What will go in the first blank? that pizza is unhealthy or that pizza is tasty?
I think the second sentence is a subordinate clause? so should the first blank be tasty?
First thing I suggest you is to Stop dealing with self made hypotheticals, not to bring you down but what I am trying to say is that “context” is important. We can’t make up that like ETS.
Nevertheless, in your example, the first blank should be Synonym of tasty, maybe something like delicious etc. If there’s a different context it can also be Synonym of unhealthy
