Woman of influence made garden fancy (6,4)
I believe the answer is:
grande dame
'woman of influence' is the definition.
'grande dame' can be an answer for 'woman' (grande dame is a kind of woman). I am unsure of the 'of influence' bit.
'made garden fancy' is the wordplay.
'fancy' indicates an anagram.
'made'+'garden'='madegarden'
'madegarden' is an anagram of 'GRANDE DAME'.
Can you help me to learn more?
(Other definitions for grande dame that I've seen before include "Venerable lady" , "Older woman revered in her own field" , "Very influential woman" , "dominant lady in a field" .)
