Hinted at or suggested (7)
I believe the answer is:
implied
I believe this clue is a double definition.
'hinted at' is the first definition.
(I've seen this in another clue)
'suggested' is the second definition.
(implying is a kind of suggesting)
(Other definitions for implied that I've seen before include "Indicated by suggestion" , "Tacit" , "Understood" , "Insinuated, hinted" , "Stated indirectly" .)
