Whale of flair or quality (7)
I believe the answer is:
rorqual
'whale' is the definition.
(I know that rorqual is a type of baleen whale)
'of flair or quality' is the wordplay.
'of' indicates the answer is hidden within the clue.
'RORQUAL' is hidden within 'flair or quality'.
(Other definitions for rorqual that I've seen before include "Large baleen whale" , "Huge beast" , "Toothless creature" , "Finback whale" , "whalers' target" .)
