Sad-sounding creature that flies and talks, it's said (5)
I believe the answer is:
minor
'sad-sounding' is the definition.
(I've seen this in another clue)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for minor that I've seen before include "Smaller - child" , "Young person below voting age" , "One hasn't reached legal majority" , "Not major" , "Of lesser importance" .)
