Nothing before loud result is important (2,11)
I believe the answer is:
of consequence
'important' is the definition.
(I've seen this before)
'nothing before loud result' is the wordplay.
I cannot quite understand how this works, but
'nothing' could be 'o' (looks like zero - 0) and 'o' is found in the answer.
'loud' could be 'f' (short for forte - 'loud' in music) and 'f' is located in the answer.
'result' could be 'consequence' (synonyms) and 'consequence' is found in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'is' is the link.
Can you help me to learn more?
(Another definition for of consequence that I've seen is " Important".)
