She was one of his creations (7)
I believe the answer is:
haggard
'one of his creations' is the definition.
Both the definition and answer are adjectives. Perhaps they are linked in a way I don't understand?
'she' is the wordplay.
I cannot really understand how this works, but
'she' could be 'ag' and 'ag' is present in the answer.
This may be the basis of clue (or it may be nonsense).
'was' is the link.
Can you help me to learn more?
(Other definitions for haggard that I've seen before include "Careworn - novelist" , "Looking exhausted and drawn" , "Englishman who wrote" , "writer" , "Lean" .)
