Suggested the din could be modified (6)
I believe the answer is:
hinted
'suggested' is the definition.
('hint' can be a synonym of 'suggest')
'the din could be modified' is the wordplay.
'the din' anagrams to 'HINTED'.
But, I am unsure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for hinted that I've seen before include "Gave clue" , "Made an indirect suggestion" .)
