Droopy writer of the French soul composition (9)
I believe the answer is:
pendulous
'droopy' is the definition.
Both the definition and answer are adjectives. Perhaps there's an association between them I don't understand?
'writer of the french soul composition' is the wordplay.
'writer' becomes 'pen' (something which writes).
'of the french' becomes 'du' ('of the' in French).
'composition' is an anagram indicator (letters arranged or composed in a different order).
'soul' is an anagram of 'lous'.
'pen'+'du'+'lous'='PENDULOUS'
Can you help me to learn more?
(Other definitions for pendulous that I've seen before include "Hanging loosely" , "Drooping" , "Dangling" , "Suspended" , "hanging heavy" .)
