Braved winds heroically, say (6)
I believe the answer is:
adverb
'heroically say' is the definition.
('heroically' is an adverb)
'braved winds' is the wordplay.
'winds' indicates an anagram (the letters wind around).
'braved' anagrammed gives 'ADVERB'.
(Other definitions for adverb that I've seen before include "Word modifying adjective" , "It qualifies the predicate in a sentence" , "Word such as "quickly"" , ""Quickly" is one, for example" , "Rarely is one" .)
