Screen matron adjusted to see complaint (12)
I believe the answer is:
remonstrance
'complaint' is the definition.
(thesaurus)
'screen matron adjusted' is the wordplay.
'adjusted' is an anagram indicator.
'screen'+'matron'='screenmatron'
'screenmatron' with letters rearranged gives 'REMONSTRANCE'.
'to see' acts as a link.
(Other definitions for remonstrance that I've seen before include "complaint" , "Strong protest" , "petition" .)
