Catholic dresser for the most part is more assured (6)
I believe the answer is:
calmer
'more assured' is the definition.
Both the definition and answer are comparative adjectives. Maybe they are linked in a way I don't understand?
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for calmer that I've seen before include "More tranquil" , "More on a level" , "More placid" , "More serene" , "Less agitated" .)
