It's fey, perhaps, that such an excitable woman might be called (6)
I believe the answer is:
feisty
'such an excitable woman might be called' is the definition.
I can't judge whether this definition defines the answer.
'it's fey perhaps' is the wordplay.
'perhaps' indicates anagramming the letters.
'its'+'fey'='itsfey'
'itsfey' with letters rearranged gives 'FEISTY'.
'that' is the link.
Can you help me to learn more?
(Other definitions for feisty that I've seen before include "Spirited and courageous" , "Confident, high-spirited (US)" , "Spiritedly aggressive" , "Lively and quarrelsome" , "Lively; determined" .)
