How resoundingly one can beat the opposition (6)
I believe the answer is:
hollow
This clue might be a double definition.
'how resoundingly one can beat' is the first definition.
Both the answer and definition are adjectives. Maybe they are linked in a way I don't understand?
'the opposition' is the second definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
Can you help me to learn more?
(Other definitions for hollow that I've seen before include "Not solid or genuine" , "Concave - sunken" , "Having an empty space inside" , "Dent; echoey" , "Empty - hole" .)
