The lionesses, though disturbed, are not growling (9)
I believe the answer is:
noiseless
'disturbed are not growling' is the definition.
I can't judge whether this defines the answer.
'the lionesses' is the wordplay.
'lionesses' anagrams to 'NOISELESS'.
But, I am not sure how this is indicated.
'though' is the link.
Can you help me to learn more?
(Other definitions for noiseless that I've seen before include "Silent, quiet" , "Lionesses (anag) - making no sound" , "unsound?" , "with a silencer?" , "Mum" .)
