Salacious but quiet amid endless calm (7)
I believe the answer is:
lustful
'salacious' is the definition.
(I know that salacious can be written as lustful)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for lustful that I've seen before include "Libidinous" , "Prurient" , "Sensual" , "Randy" , "Carnal" .)
